Bitcoin Breaks Record High, Now Over $3,200 After Risky “Fork” into Competing “Bitcoin Cash”

Bitcoin has Forked into Two!

Bitcoin has Forked into Two!

After squabbling for years over how to fix the growing pains of the world’s first decentralized cryptocurrency, one of the sides in the ongoing Bitcoin Geek War has finally made a bold move. This week, on August 1st, a small number of the “big blockers” performed a “hard fork” and broke away from the main Bitcoin blockchain, creating a new currency, “Bitcoin Cash“. This had the added benefit of giving everyone who already held Bitcoin an equal amount of the new Bitcoin Cash! Ever heard the phrase, “there’s no such thing as a free lunch”? Bitcoin’s first fork into two has proven that statement wrong. Read on to learn more about this historic week in Bitcoin.

The blockchain is the distributed, decentralized ledger that contains every transaction that has ever occurred on the Bitcoin network. It’s approximately 150 GB in size. Since the hard fork, there are now two “Bitcoin” blockchains competing for market dominance. Both of them have the exact same transactions from the beginning of Bitcoin nearly a decade ago, running until August 1st, 2017, when at just after 2pm Eastern time the first “Bitcoin Cash” block was mined into existence, at greater than 1 MB – in fact, its size was about 4 MB.

Since the original Bitcoin blockchain has a 1 MB limit per block, it was at this point that the one blockchain became two. The supermajority of miners are still mining the original Bitcoin chain, let’s call it “Bitcoin Core” or BTC. However, a small portion of miners have joined the mining of the new “Bitcoin Cash” or BCH. If you thought Bitcoin Core’s growing pains were challenging, take a look at how Bitcoin Cash had to start:

Bitcoin Mining

Bitcoin mining doesn’t actually look like this.

In Bitcoin, there’s a thing called mining difficulty that is basically designed to increase as more people enter mining and compete to discover scarce Bitcoins. However, should people leave the mining game, the difficulty will decrease. In BCH’s case, when they started their fork, their network was at the same difficulty level as BTC, but with a fraction of the total mining power. That’s why it took six hours for the BCH miners to find their first block! Normally Bitcoin blocks are expected to be found every ten minutes. So, this means BCH transactions were, in the beginning, taking hours to confirm! They are as of this writing, still taking longer than BTC transactions.

Worse still, no one who wanted to sell their newfound BCH was easily able to do so for at least the first couple days of its existence. Due to concerns about certain technical attacks that are possible in the time after a fork, cryptocurrency exchanges were extra cautious before allowing BCH deposits to trading accounts. However, while they weren’t allowing people to deposit BCH, they WERE allowing them to trade it. Huh? How can one trade something on an exchange to which one can’t deposit? Remember, after the fork, the people with BTC in their exchange accounts were given a balance of the same amount of BCH. (Except at the Bitfinex exchange, who screwed over their customers.) So, since trading was happening but no one could deposit, the price of the new BCH trended upward, even reaching as high as $800-$1,000 on some exchanges. (more…)
