Bitcoin Cash itself was created through another acrimonious hard fork last August. That schism was motivated by a disagreement about the size of blocks in bitcoin's blockchain. Most of bitcoin's developers favored retaining the 1 megabyte block-size limit that was in effect at the time (a hack called segregated witness has increased the effective block size since then). The hard limit contributed to severe congestion on the bitcoin network, pushing transaction fees up to a median of $34 in mid-December. Bitcoin Cash supporters created their own version of bitcoin with a much higher 8 megabyte block size limit (later raised to 32 megabytes)—allowing this rival version of bitcoin to process many more transactions per second with negligible transaction fees.
Coinbase Pro (formerly known as GDAX) is a serious trading platform with screens that look familiar to those who use Bloomberg terminals or active stock, commodity and option trading platforms. It charges fees ranging from 0.10 percent to 0.30 percent based on your trading volume. Most people trade less than $10 million per month and will fall into the 0.30 percent tier. If you want to try Coinbase but with much higher volume, this platform is the way to go.

Bitcoin cash is a different story. Bitcoin cash was started by bitcoin miners and developers equally concerned with the future of the cryptocurrency, and its ability to scale effectively. These individuals had their reservations about the adoption of a segregated witness technology, though. They felt as though SegWit2x did not address the fundamental problem of scalability in a meaningful way, nor did it follow the roadmap initially outlined by Satoshi Nakamoto, the anonymous party that first proposed the blockchain technology behind cryptocurrency. Furthermore, the process of introducing SegWit2x as the road forward was anything but transparent, and there were concerns that its introduction undermined the decentralization and democratization of the currency.

Design issues. Despite Bitcoin's massive rise in popularity over the past several years, it is not immune to design problems. For example, starting late last year Bitcoin transaction speeds became very slow because of a scaling problem related to the way the Bitcoin blockchain works. (You can read the details here.) That issue did not end up creating the existential crisis for Bitcoin that some analysts predicted, and the problem has now more or less been solved via something called SegWit. Still, the Bitcoin scaling issue was a reminder that a new type of serious problem may creep up in the future that undoes Bitcoin.
There is also the Bitcoin Investment Trust from Grayscale Investments. We’re mentioning it for the sake of comprehensiveness, but it’s a bit of a different animal. The fund is invested in bitcoin, but keep in mind, you’re actually buying the fund, not bitcoin. You’re a step removed from owning actual bitcoin, even though you are still exposed to its volatility. The pluses, Grayscale says on its site, are that you get the structure and tax benefits you wouldn’t get trading bitcoin directly; on the other hand, fees will eat up a chunk of anything you earn, negating the reason many people are drawn to cryptocurrencies in the first place. All of which is to say, you should really, really know what you’re doing as an investor if you’re going to dive into this pool.
If having an account at a bitcoin exchange is like having a seat at the NYSE, then doing business with a bitcoin broker is like having an e*Trade or Charles Schwab account. The advantage of using a broker is simplicity. The customer asks for a quote, places an order, and receives what they asked for, and the broker removes the complexity of dealing with an exchange.
Second, two coins could survive the split, both with their own name and ticker. (In this case Bitcoin ABC seems most likely to get the name “Bitcoin Cash” and “BCH,” but this could differ from one service to the next.) This is where you need to be particularly careful, as there’s no replay protection. When you send one coin you may unintentionally send the other along with it — or vice versa. To avoid this, you need to first split your coins by using a splitting tool, for example, or by sending your coins to an exchange or other type of service that will split the coins and send both back independently. (Again, there’s no rush to do any of this. Until you know what you’re doing, it’s best to do nothing at all.)
The largest bitcoin exchange in the world at the moment in terms of US$ volume is Bitfinex, although it is mainly aimed at spot traders. Other high-volume exchanges are Coinbase, Bitstamp and Poloniex, but for small amounts, most reputable exchanges should work well. (Note: at time of writing, the surge of interest in bitcoin trading is placing strain on most retail buy and sell operations, so a degree of patience and caution is recommended.)
There isn't a way to invest in Bitcoin the way you would invest in the stock of a company. But depending on the long-term plan for your newfound cryptocurrency, buying Bitcoin and monitoring its value can technically make you an investor of sorts. By attempting to buy bitcoin at the lowest price and sell at a higher rate, you could make money off your purchase like an investment.

The would-be hard fork with an expanded block size limit was described by hardware manufacturer Bitmain in June 2017 as a "contingency plan" should the Bitcoin community decide to fork; the first implementation of the software was proposed under the name Bitcoin ABC at a conference that month. In July 2017, the Bitcoin Cash name was proposed by mining pool ViaBTC.

Because the computer power required to process larger blocks could price out some smaller miners, critics worry that adopting Bitcoin Cash’s approach will lead to power being concentrated in the hands of companies that can afford more and better equipment. Opponents to the fork worry that this will threaten the consensus-driven approach to Bitcoin, as a small number of companies could control Bitcoin and more readily force changes on the community in the future.
While all this is very speculative, Bitcoin ABC could defend itself against such an attack in several ways, too. For one, Bitcoin ABC users could simply wait out the attack, as it costs the attackers money every hour, and this cannot last forever. Alternatively, (Bitcoin) miners could opt to draw more hash power from the Bitcoin blockchain to mine on the Bitcoin ABC chain, or deploy more hash power altogether. (Some news sources claim Bitmain is indeed doing this.) Or, in what is typically considered the “nuclear option,” Bitcoin ABC could choose to deploy another hard fork to change the proof-of-work algorithm, rendering the attacking mining hardware incompatible with its blockchain. (Bitcoin ABC lead developer Amaury Séchet has already acknowledged this option is on the table.) There may be other countermeasures too, like less radical protocol changes.
But before we get to the tutorial steps, it's really important to know what we're getting into. Increasingly I hear from students making mistakes due to rushing into Bitcoin because of all the hype. There's so much fragmented or misleading information out there. My aim here is to strip it to total basics without putting you off for another 4 years (hopefully).
Today Bitcoin (BTC) 00 got nuked. In fact, the entire cryptocurrency market took a direct hit from a 50 megaton hydrogen bomb — and it looks like it’ll take a while for the smoke to clear. Novogratz was wrong, Tom Lee was wrong, everyone who thought $6,000 was the bottom was wrong. Analysts will probably spend the rest of the week attempting to determine the sources responsible for the turmoil.

IBM (IBM) has developed blockchain technology that they are using with a large variety of partners in a large variety of industries. One example is their partnership with food retailers, most notably Walmart, to help quickly, efficiently, and securely track the supply chain to help ensure ideal food safety. They have also partnered with Maersk to work on a blockchain platform for global trade.
A hard fork is when developers and miners no longer agree on a proposed change to the software, despite operating on the same blockchain. Once the fork takes place, one group of so-called nodes — computers that are connected to the network and are part of the transaction confirmation process — will upgrade to the new software and the other will operate on the old rules, creating two separate blockchains and digital currencies.
In 2017, the Bitcoin project and its community split in two. Perhaps the least controversial way to refer to each side is simply by their respective ticker symbols, BTC and BCH. Bitcoin Cash is usually represented by the BCH ticker symbol and is considered by its supporters to be the legitimate continuation of the Bitcoin project as peer-to-peer digital cash.
These days, stocks in the US are regulated by the Securities and Exchange Commission, precisely, because in the olden days, there were many stocks issued that were much like bitcoin, marketed to unsophisticated investors as a get-rich-quick scheme. The very definition of this investor is: “Being more willing to buy something the more its price goes up.”

Since very few countries in the world are working on regulation of Bitcoin and Cryptocurrency in general, these exchanges can be shut down. This happened in China sometime in September 2017. Exchanges are also at risk of getting hacked and you might lose your Bitcoin if you store it on an exchange. You can read about the biggest Bitcoin hacks here.


As the legend goes, in 2008 an anonymous developer published a white paper under the fake name Satoshi Nakamoto. The author was evidently a software and math person. But the paper also has some in-built ideology: the assumption that giving national governments the ability to monitor flows of money in the financial system and use it as a form of law enforcement is wrong.

Ayre, Wright, and their sizable number of supporters seem to share a very specific vision for cryptocurrency, and it seems that only complete capitulation of their peers would be enough for them to call it quits this far in. A whole generation of Bitcoin mining hardware is soon to be obsolete with next-generation miners coming online, and this soon-to-be-resold hardware has a convenient retirement plan: mine on one or all of the latter-day Bitcoin blockchains. Effectively, a dedication or rededication of any significant amount of hash power from unexpected sources to either chain would change outcomes significantly, and this possibility relies very much, of course, on the market performance of either.
If you want to trade in cryptocurrencies, you’re going to need a platform on which to trade them, and an intermediary to communicate within the network of traders. Most of us lack the technological inclination or means to mine Bitcoin directly, or communicate and trade with miners directly, or store our digital currencies and assets. That’s where Coinbase comes in.
A Segregated Witness solution implied storing some of the information in separate files outside of the Blockchain. Developers claimed that it would free up a lot of storage space, the blocks will fit in more transactions and the confirmation time will significantly decrease. But, many people believed it was just a more complicated temporary stopgap when compared to the Bitcoin Unlimited approach.
Bitcoin Cash (BCH) is released on 1st August 2017 as an upgraded version of the original Bitcoin Core software. The main upgrade is the increase in the block size limit from 1MB to 8MB. This effectively allows miners on the BCH chain to process up to 8 times more payments per second in comparison to Bitcoin. This makes for faster, cheaper transactions and a much smoother user experience.

As I mentioned earlier, Bitcoin is not like a typical currency that you keep in your bank. You are responsible for the security of your Bitcoins and that’s why you keep it in a wallet that you have 100% control over. This is done by having the ownership of seed word or private key.  For the first timer, it may sound very technical, but it is actually easy to understand and learn.

There's so much fragmented or misleading information out there. My aim here is to strip it to total basics without putting you off for another 4 years (hopefully).
If you’re aware of the risks and still willing to take the plunge, this is what you need to know about investing in bitcoin: Cryptocurrencies exist in an unregulated, decentralized digital sphere without involvement by (or protection via) a central bank. This is part of bitcoin’s appeal. People or entities can buy and sell cryptocurrency anonymously, and there are fewer middlemen taking a cut of transactions. But it also means you can’t just buy bitcoin via mainstream investing tools like a brokerage account.
Hardware wallets are the option I recommend for storing your Bitcoin. They allow you to store your Bitcoins offline on a small piece of hardware. You plug the hardware wallet into your computer (with a USB) and transfer your Bitcoins on to it. This allows you to store your Bitcoin offline so that they can’t be hacked. When wondering how to invest in Bitcoin, I would definitelly go for the most secure wallet.
To sell your Bitcoin or other cryptocurrencies on an exchange after purchasing, just go to the appropriate page or tab, for example, Coinbase has a Buy/Sell tab where users can buy and sell on the same page. Most exchanges will charge a fee for selling, usually around 1%-2%. The exchange CEX.io will allow users to sell Bitcoin and receive funds directly to their credit card.
