What is Bitcoin Cash? — a short guide


Bitcoin Cash is a cryptocurrency that’s very similar to Bitcoin, Litecoin, and many others that are on the market. It’s a form of digital money you can use to buy goodies online or make it a part of your investment portfolio.

Like most other cryptocurrencies, Bitcoin Cash is decentralized, which means it’s not managed by any authority like a central bank. It’s a form of payment that cuts out the middleman, which should speed up transactions and reduce the high fees charged by financial institutions like banks and PayPal.

Bitcoin Cash offers complete anonymity when making and receiving payments. Although each transaction is recorded and displayed on a publicly disclosed blockchain, you don’t have to share your personal info such as a full name, address, and so forth when doing business with the cryptocurrency.

It’s created through a process called mining, which involves solving complex math puzzles that can require specialized computer equipment. The first miner to solve it is rewarded with some of the Bitcoin Cash created. The same process applies to the creation of most other cryptocurrencies including Bitcoin, Ethereum, and Dash.

What makes it different from Bitcoin?

The Merkle

Bitcoin has had a problem built into it since its inception – scalability. It has a small 1 MB block size limit, which makes it extremely slow. It’s the largest cryptocurrency in the world but is said to only be able to handle seven transactions per second. For comparison, Visa can handle 24,000 transactions in the same time.

Additionally, Bitcoin transactions also take 10 minutes to process and have become expensive because of high demand — typically more expensive than doing business through banks. According to BitInfoCharts, the average transaction fee currently stands at around $1.5 but was as high as $55 back in December 2017.

These are the two problems — scalability and high fees — that Bitcoin Cash is trying to solve. The cryptocurrency was created by a group of influential miners, developers, and investors on August 1, 2017, when they initiated what is known as a hard fork in the Bitcoin blockchain.


The major difference between Bitcoin and Bitcoin Cash is that the latter has a block size limit of 8 MB — eight times larger than its biggest rival. This speeds up transactions as well as reduces fees. These come in at around $0.1 per transaction, making Bitcoin Cash a way more affordable option than Bitcoin.

Aside from the block size limit, Bitcoin Cash and Bitcoin are more or less the same. One isn’t better than the other — they are just different. Both are created in the same way and can be used for making transactions online or investment purposes. Demand for cryptocurrencies is more than big enough at the moment for both to co-exist on the market, along with many other competitors.

Where can you buy, store, and spend Bitcoin Cash?

Bitcoin Cash A few Bitcoin Cash exchanges

Buying Bitcoin Cash is a breeze. You can get it from many online exchanges including Bitstamp, Coinbase, and Kraken — see full list here.

But before you buy it, you have to know where to store the cryptocurrency. There are a few different options available, with one of them being hardware wallets like the Ledger Nano S and Trezor. You can also opt for a desktop wallet such as Jaxx, Exodus, and Electron Cash. Visit Bitcoin Cash’s website to see more providers.

Bitcoin Cash isn’t accepted by as many companies as Bitcoin, but there are still many places online where you can spend it. You can buy all sorts of products and services with the cryptocurrency such as hosting, accommodation, and much more.

Should you invest in Bitcoin Cash?


Although there are many ways you can spend Bitcoin Cash online, most people buy it for investment purposes. Bitcoin Cash is currently the fourth largest cryptocurrency in the world by market cap behind Ripple, Ethereum, and Bitcoin.

So far, it has proven to be a good investment. Bitcoin Cash went for around $250 at launch and quickly started gaining value. It reached its peak in December when you could get one for $4,300, according to the price chart provided by CoinMarketCap. However, its price went down significantly since and currently stand at around $920.

If you invested $1,000 in Bitcoin Cash in August 2017 when one went for $250, you would have $3,680 today.

Let’s put things into perspective by crunching some numbers. If you invested $1,000 in Bitcoin Cash in August 2017 when you could get one for $250, you would have $3,680 today. But if you’d be smart enough to sell it when its price hit an all-time high — which is hard to — you’d have $17,200. That’s a fantastic ROI (return on investment), especially when compared to savings accounts offered by banks. However, it’s lower than what you’d get with a few other cryptocurrencies like Litecoin.

Editor's Pick

In which direction the price of Bitcoin Cash will go in the future is anyone’s guess right now. Just because it’s proven to be a great investment for some — especially those who bought it at launch — doesn’t mean the same will be true in the future. An important thing to keep in mind is that cryptocurrencies are extremely volatile, which means their price can go up or down substantially in a short period of time. This makes them way less stable than fiat currencies like dollars and euros.

To give you an example, the price of Bitcoin Cash went down from $4,300 on December 20 to around $2,000 on December 22. That means the cryptocurrency lost approximately 54 percent of its value in just two days! With that in mind, make sure you don’t invest more money into Bitcoin Cash and any other cryptocurrency than you can afford to lose.

Do you buy new, used, or refurbished phones? [Poll of the Week]

Last week’s poll summary: Out of over 9,500 total votes, 68% of our readers said they have not received an update to Android Oreo yet. That’s not surprising, considering the last Android distribution numbers showed Oreo installed on just 1.1% of all smartphones.

People aren’t buying brand-spanking-new smartphones as often as they once were, and that’s due to a couple different factors — increasing smartphone prices, lack of innovation, or the simple fact that last year’s smartphones can perform just as well as this year’s phones.

Also read

All three of these points combined make for a difficult case to buy the latest and greatest phone on the market. If 2017 or or even 2016’s flagships aren’t lacking too much in any particular area, why not save some money and go for the older model? Or better yet, why not spring for a refurbished smartphone instead? A lot of the time, refurbished phones come with manufacturer warranties, which means you won’t be completely out of luck if your phone has a problem.

I usually tell my family to buy “new” phones from the previous generation, or go the refurbished route. But what about you? When it’s time to upgrade, do you buy new, used, or refurbished smartphones? Cast your vote in the poll attached below, and speak up in the comments if you have anything to add.

Honor View 10 international giveaway!

Welcome to the Sunday Giveaway, the place where we giveaway a new Android phone each and every Sunday.

A big congratulations to last week’s winner of the Samsung Galaxy S9 Plus international giveaway: Leonard J. (Philippines)

This week we are giving away a brand new Honor View 10!

Just because a phone is packed with high-end features, doesn’t mean it has to have a high-end price. The Honor View 10 ticks many of the boxes most smartphone owners want, and it does so at a sub-$500 price point.

The View 10 features Huawei’s AI-powered Kirin 970 chipset, which was previously only available on the Mate 10 and Mate 10 Pro. Of course, that Kirin 970 means you’re also getting access to the dedicated Neural Processing Unit (NPU), which allows the phone to recognize objects in the camera and automatically select the mode to best fit the subject you’re trying to shoot.

What’s more, the NPU also automatically optimizes the phone’s memory based on which apps are used most often. Of course, RAM management shouldn’t be much of a problem anyway, considering the Honor View 10 comes with 6 GB of RAM. There’s also 128 GB of storage, expandable memory up to 256 GB, as well as a hybrid dual-SIM tray.

In our full review, we were really impressed by the View 10’s dual-camera setup, which features a 16 MP f/1.8 aperture color sensor and a 20 MP f/1.8 aperture monochrome sensor. Not only can it take solid pictures, it also offers plenty of fun features like portrait and wide-aperture modes.

The surprising growth of used smartphones

Used smartphones

While the global smartphone market saw a steep fall in sales in the last quarter according to all major research agencies, the used smartphone and refurbished market is gaining traction at a surprising rate.

This is important because the numbers show that the smartphone market declined by between 5 and 9 percent in the last quarter of 2017 (depending on whose report you’re reading). This is a significant drop. But that was just the new smartphone market — research from Counterpoint’s refurbished smartphone tracker shows a 13 percent leap year-on-year. That’s 140 million units changing hands, which is close to 10 percent of the entire market.

Second-life devices now represent close to 10% of the entire smartphone market

These “second-life” devices include repaired smartphones, “rejuvenated” models, or just those collected and sold as is. Combined with the fact we’re holding onto phones longer, the increasing sales of second-hand phones is reducing new smartphone demand, as Counterpoint research director, Tom Kang, confirms:

“The slowdown in innovation has made two-year-old flagship smartphones comparable in design and features with the most recent mid-range phones. Therefore, the mid low-end market for new smartphones is being cannibalized by refurbished high-end phones, mostly Apple iPhones and, to a lesser extent, Samsung Galaxy smartphones.”

Apple and Samsung devices in the refurb market, Counterpoint says, hold close to 75 percent of the second-hand market, with Apple “leading by a significant margin.”

Apple says it doesn’t mind this at all, and I’ve previously talked about how Tim Cook’s philosophy that the “more people on iPhone the better” is exactly right for Apple’s ecosystem approach: get people in early via hand-me-downs and lock them in. In fact, Apple even tried to get a foothold in India by attempting to convince the government it could sell used iPhones to Indian consumers. India’s government disagreed.

The refurb market is further boosted by other factors too. Third-party-repair store fronts and guides from iFixit make it cheaper and easier to replace a broken screen or put in a fresh battery than ever before. Meanwhile, the right-to-repair movement is gathering steam in its attempt to make this far easier than it is now, with a lack of easy access to a device’s innards still a problem.

Editor's Pick

Another big factor for the improving fortunes of our old phones is that new phones just aren’t as tempting as they once were. Rob Triggs made a strong point recently that innovation saturation has occurred in the smartphone market, where multiple brands are embracing a safer “tick-tock” mobile strategy, replacing the need for annual upheaval.

The Samsung Galaxy S9 is the perfect example of refinement over the earlier S8 — small design improvements, better specs, and a handsome RRP, for those that just want the latest. Similarly, the iPhone 7s represents only incremental improvement over the iPhone 7, but it’s still a better device. And, as Rob mentioned, these small steps allow companies to bide their time on introducing the Next Big Thing. This approach favors perfecting tech rather than rushing new devices. Sony and OnePlus, on the other hand, are playing the much tighter six-month cycle, while LG is one example of a major shift in the industry: an end to yearly upgrades:

We plan to retain existing models longer by, for instance, unveiling more variant models of the G series or V series.

“We will unveil new smartphones when it is needed. But we will not launch it just because other rivals do,” said LG Electronics vice-chairman Cho Seong-jin.

“We plan to retain existing models longer by, for instance, unveiling more variant models of the G series or V series.”

While cameras, processors, and screens are all getting better, the vast majority of premium smartphones from the last two years are eminently capable.

There’s a growing level of sophistication to the second-hand market, where resale values are well understood. Counterpoint’s research director, Peter Richardson, added in their report that it’s a truly global phenomenon:

“Regions seeing the highest volume include the U.S. and Europe. While the fastest growing markets for refurbs include Africa, SE Asia, and India. All have been seeing initiatives from the major operators (e.g. Verizon, Vodafone etc.), OEMs (e.g. Apple), and major distributors (e.g. Brightstar) who are adding full life-cycle services.

“The industry uses data analysis to predict future resale values of devices, which means consumers can be given a guaranteed buy-back value at various points during their ownership […] Overall, we expect this trend to continue gathering pace.”

We had a detailed look at which smartphones retain their resale value best:

Used smartphones

The key takeaway is that grabbing a phone from a well-known and trusted brand is important — Apple, Samsung, and the Google range have held up best. We also found resale price drops on 2016 smartphones were around 25 to 30 percent, while 2017 showed drops closer to 20 to 25 percent, implying that as the used smartphone market grows, resale value increases as well.

As the used smartphone market grows, resale value increases as well.

A look at camelcamelcamel.com indicates that retail value on a 64 GB iPhone X has fallen approximately 17 percent since launch. The Samsung 64 GB Galaxy S8 has only fallen around 18 percent since launch, which isn’t bad considering the S9’s subsequent debut. (It is worth noting that there have been a number of sales pushing the total discount up to 21 percent.)

Overall, while we can figure out some good reasons behind this, it’s still surprising. Only 25 percent of devices are making it back onto the market, which is still low. We hear a lot about planned obsolescence in our devices preventing enjoyable usage beyond the 18-24 month mark, and that may be one reason that 75 percent of devices don’t get put back on the market, along with hand-me-downs to family and friends not being tracked.

But with the sector growing, it might be time to consider the resale value of your current device, and how your next device’s value will hold up. It’s a safe bet to say that if the industry continues to struggle to create real innovation, and important elements like cameras and screens only go from very good to very very good, we’ll continue to see second-hand smartphones as genuinely good options.

For the industry that needs to keep selling premium devices, the pressure is on to make the high-end market continually enviable for those with last year’s models, and convince the mid-range community not to simply buy those used flagships instead.

Top 10 Galaxy S9 Settings to Change

Top 10 Galaxy S9 Settings to Change is a post by Cory Gunther from Gotta Be Mobile.

If you just picked up the Galaxy S9 or Galaxy S9+ there are a lot of fun new features to play with and learn. In fact, there are several Galaxy S9 settings to change or features you can enable for a better experience. With those tips in mind, here we’ll go over the first 10 settings you should change.

Some of our tips and tricks we do on every Galaxy phone, while others are new to the Galaxy S9. Including enabling full screen apps, using intelligent scan and more. Use these tips to personalize your phone and do more with it at the same time.

Enable Full Screen Apps on the Galaxy S9

The first thing you’ll want to do is make sure every app or game you enjoy takes advantage of the entire screen. Samsung’s beautiful new 5.8 or 6.2-inch screens are taller and skinnier than older phones. As a result, some apps don’t use the fullscreen and you’ll have black bars on the top and the bottom. This aspect ratio doesn’t work right with a few apps, but we can force them into full-screen mode.

Here’s how to enable full screen apps. Or, Just head to Settings > Display > Full Screen Apps > and enable any app that isn’t highlighted.

We specifically had to toggle Snapchat and Clash Royale to use the full 6.2-inch S9+ screen. That said, almost everything else works perfectly. Bonus tip: pinch to zoom will expand YouTube to full screen on the S9.

Setup Iris Scan & Face Unlock (Intelligent Scan)

Older Samsung phones had facial unlock features or Iris scanning, but the Galaxy S9 takes those a step further. There’s an all-new lockscreen and security option listed as Intelligent Scan, and you’ll want to quickly set it up and use it.

It’s a biometric security and authentication method similar to your fingerprint, only an Iris is even more secure. Intelligent Scan uses both Face unlock or Iris scanning, or both, to unlock your phone as fast as possible. To start, go to Settings > Lock screen and security > Intelligent Scan and follow the prompts to get all set up.

Turn on Quick Launch Camera

One of our favorite Galaxy features is being able to quickly launch the camera at any moment. Perfect for getting photos in any situation, even when the screen is off. Simply double-tap the power button very quick, and the camera will fire up. Then, select “yes” to keep Quick Launch turned on. Or, follow these instructions

Open the camera, go to settings and enable “Double Tap Power Button to Quick Launch Camera”. Now, no matter what you’re doing double tapping the power button will instantly start Samsung’s new dual aperture camera. Snap some photos or quickly record a slow-motion video.

While you’re in the camera settings turn off shutter sounds, and even turn on voice controls so you can snap photos hands-free.

Add an SD Card and Set Camera to SD Storage

We recommend adding a microSD card to your Galaxy S9 so you have extra space for apps, games, music, and videos. Here are some of the best cards you can buy right now. Then, watch our quick video below on how to add an SD card, followed by the steps to make your camera instantly save everything to it. That way you won’t waste precious internal storage on all the photos and video you’ll be shooting.

Once you install a microSD card you’ll want to switch everything to it. Fire up the camera app, tap settings, and scroll down to “storage location” and set it for “SD Card” rather than internal storage.

Change the Screen Resolution to Quad-HD

You paid for a phone with a beautiful 2560 x 1440 Quad-HD AMOLED display, so use it. Out of the box, Samsung has it set to 1080p Full HD, but we can quickly change it.

The Galaxy S8 and S8+ ship with the screen in FHD+ mode. This may help with battery life, but it also means you aren’t getting the full resolution that the screen can offer. Upgrade your screen instantly in settings.

Go to Settings and search for Screen resolution. Slide it over to WQHD+ 2,560 x 1,440 and hit Apply.

Setup Do-Not-Disturb & Night Mode

Do-Not-Disturb is a great feature that everyone should use. It works great on the Galaxy S9 and only takes a moment to set up. I have Do-Not-Disturb to automatically come on at 10:45 PM each night, and turn off at 6:30 AM. That way nothing bothers me while I’m sleeping.

Head to Settings > Sounds & vibrations > and scroll down to “Do-Not-Disturb” and turn it on with a set schedule. Owners can even customize it so alarms can still get through, or repeat callers in case of an emergency. There are even exceptions like specific friends or family members can still call or text you, while everything else gets silenced until morning. We highly recommend using this.

Then, take advantage of the Blue light filter which works like Night Shift on the iPhone. Go to Settings > Display > Blue Light Filter and customize this too. I have it set to a schedule to come on at night, and turn off in the morning.

What does this do? It actually eliminates blue light from the screen. This helps prevents eye strain and reportedly helps calm the brain at night so you fall asleep easier and faster The blue light is a stimulant, apparently.

Get Your App Drawer Button Back

If you recently switched to the Galaxy S9 from an older Samsung or another Android device, you’ll likely miss the app drawer button. Basically, the white button that launches a tray with every app or game on your phone. Samsung removed it, and you must swipe upwards to launch your app drawer. There’s no reason to waste space with a button dedicated to the drawer.

We’re creatures of habit, so here’s how to get it back. Long press a blank space on your screen like you do to add a new wallpaper. This brings up the layout and edit homescreen menu. Tap the gear-shaped settings button. Next hit the option in settings labeled Apps Button and select show apps button. Now hit done and go back. You’ll have that familiar white app launcher icon back.

Disable Bloatware

Don’t get me started on bloatware, those apps that come pre-installed on your phone you’ll never ever use. It’s getting out of hand, especially on AT&T phones. Bloatware is a never-ending battle with smartphones unless you buy unlocked devices. Carriers add these apps as partnership deals to make money, and we have to deal with them wasting space on the Galaxy S9. However, we can disable them to clean up the app tray. Basically, out of sight, out of mind.

Go to Settings > Apps > and simply start scrolling down the list and disable anything from AT&T, T-Mobile, Verizon, or Sprint. As you see above I’ve selected AT&T Call Protect Blocking (an app I don’t want to pay monthly to use) and then just hit Disable. This is as close to uninstalling bloatware and junk apps as you’re going to get without modifying your phone.

I disabled everything from Amazon, AT&T, AT&T Data Usage Manager, Lookout Mobile Security and a few others. Same goes for Verizon apps, T-Mobile stuff, and Sprint NASCAR additions. Use caution here and only disable things you understand and know what they are. Otherwise, you could cause more harm than good, or turn off features your phone needs.

Use and Customize the Always-On Display

One of the best features over the last few years is the Always-On display. Samsung’s Galaxy S9 screen can give you quick at-a-glance information about the time, date, weather, battery levels and incoming notifications. Even when the screen is off. A small area stays on all the time, as the name suggests. Turn this on, enjoy it, and customize a few of the options.

Head to Settings > Lock screen and security > Always On Display to get started. You can select what does, or doesn’t, show up on the lock screen. Next, go to Settings > Lock screen and security > Clock and FaceWidgets to change the clock styles, colors, or widgets. You can also add background images, a GIF, calendar and more in a low-power always-on state.

Samsung Theme Store, Samsung Pay & More

And for this last category, we wanted to highlight a few other settings to change or things to try that we think are important or worth it. The first one being Samsung’s theme store. It’s extremely powerful and gets better every year. Go to Settings > Wallpapers & themes > and look around. You can customize the entire look and feel of the phone, change the icons, or heavily modify the Always-on display. I’m running a stock Android theme with Google Pixel icons, so my Galaxy S9 looks closer to stock Android.

Customize as much as you’d like and make the Galaxy S9 your own. We also recommend heading to Settings > Display > Navigation Bar > Button Layout to change the on-screen buttons. You can reorder them however you want, so it matches your last phone. That way you don’t keep accidentally hitting the back button.

Next, Samsung Pay is by far the best mobile payment system available, so enjoy it. You can use your Galaxy S9 to pay for stuff anywhere Apple Pay or Google Pay works, known as NFC terminals. However, it’s also backward compatible with magnetic swipe card terminals (MST) and works at 95% of stores in the United States. It’s incredibly convenient. Click the Samsung Pay app to get started.

Final Thoughts

We also recommend trying Smart Lock. Just go to settings and type “Smart Lock” in the search bar at the top. Once configured, the Galaxy S9 will know when you’re home, connected to a watch or Bluetooth stereo, or at work and will bypass any lock screen security system. Basically, the phone knows when it’s safe to skip a password, pattern, pin or fingerprint so it’s easier to use. Once you leave, the lock screen security kicks into place. That way you’re not using your eyes or fingerprint to unlock the phone when you’re sitting on the couch at home.
