From $980 to $4,740: The Year Bitcoin Split in Two

From $980 to $4,740: The Year Bitcoin Split in Two

A bitcoin was worth $980.29 on January 1, 2017. By October 9 of that year, it was trading at $4,740. In those nine months, the community that had supported the digital currency for nearly a decade fractured in two: on one side, those who saw it only as the original store of value; on the other, a tide of alternative coins poised to take over the market by promising returns that Bitcoin no longer offered. The catalyst for the split wasn't the price. It was a fork and a fight for control of the software.

The Day Bitcoin Cloned Itself

On August 1, 2017, the Bitcoin Cash hard fork was executed. The new chain was born for those who wanted larger blocks and cheaper transactions. On paper, a simple change of parameters. In practice, a coordination failure. It took over three hours to see the first block mined. While half the market debated whether it even existed, some exchanges were already trading the newborn coin for fiat money. 'Without a first block, Bitcoin Cash doesn't exist yet,' many warned. Others retorted that the inertia of a consolidated chain had already been lost forever.

The price soon proved the skeptics right. Weeks later, Bcash was trading at 288 euros compared to 3,900 for the original Bitcoin. That drop became the definitive argument for the purist faction, which has repeated the same phrase ever since: you can't fork a decentralized network and keep the name too.

Segwit, Scaling, and the Block Wars

The underlying problem had gone unresolved for years: Bitcoin couldn't keep up. With one-megabyte blocks, the network could only process a handful of transactions per second, and during peak demand, the mempool—the queue of pending operations—became clogged with soaring fees. At the end of August 2017, Segregated Witness was activated, a soft fork that reorganizes how data is stored and quadruples the effective block capacity. The key, technicians explained, is that it allows payments to be moved off-chain with the so-called Lightning Network: only the final result is recorded, not every single movement.

The fight wasn't technical; it was about power. One side wanted larger, faster blocks; the other, external layers and conservative development. 'The leadership of the BCH fork was in the hands of a handful of developers and miners,' argued the critical sector, for whom the real objective was never to enlarge the block, but to seize control of the original software repository. Miners, meanwhile, saw their business threatened: in an external layer system, they only collect the fee for the final result, not for each payment.

The Mempool Emptied, and No One Knew Why

One of the mysteries left open was that of the saturated mempool. For months, the network was jammed, and many blamed the increase in users. When the congestion disappeared suddenly, another theory emerged: 'Someone was spamming the network with transactions to force up fees and push for large blocks.' The suspected culprits were miners with an interest in the debate. The case was never closed.

What could be measured was the Segwit effect. A transaction with the minimum fee—around 0.01 millibitcoins, about four cents—achieved seven confirmations in an hour. In September 2017, barely 1% of transactions were already using the new format, but the adoption by commercial wallets was expected to drive it up. This figure contrasts with the collapsed network fruta it had carried for months prior.

The Returns Some Missed Out On

Here's the blow for the converts. Anyone who had put $980.29 into Bitcoin on January 1, 2017, and left it untouched would have had $2,000 by May 24: a little more than double. The same amount in Ethereum, which started at $8.09 and reached $200, would have turned into $24,234. In DASH, from $11.38 to $153, it would have been $13,179. And in XRP, from $0.0064 to $0.34, the stake would have reached $52,077. The calculation circulated like a hammer blow: loyalty to the mother coin was proving very costly compared to betting on alternatives.

The veterans' response was always the same: 'Bitcoin is everything, and everything is Bitcoin or whatever comes next.' A reasoning that sounded like a slogan to newcomers. For the purist camp, the other coins weren't competition but speculative noise that always ended the same way, devoured by their own volatility.

Arbitrage Between Exchanges and the Price That Doesn't Add Up

That year yielded another uncomfortable fact: the price of Bitcoin depended on where you looked. On the same day, Bitstamp quoted it at $4,196.62, Bitfinex at $4,196.8, and China's OkCoin platform at $4,084.36. A difference of $112 per coin between markets. In Zimbabwe, the only local exchange sold it at $6,646.99. Arbitrage seemed like the business of the century until someone tried it: liquidity was so ridiculous that it didn't cover the transport costs.

This dispersion left a sarracena that the sector repeats every time there's a crash: when someone says bitcoin has reached X thousand, you have to ask on which exchange. A market trading with more than a 10% difference between platforms isn't mature.

Can Bitcoin Be Banned?

The recurring antiestéticar was the reaction of states. Shutting down exchanges, persecuting those who accept the currency, going after miners. The most repeated argument to dismiss it was geographical: 'A state cannot shut down a platform located in another country that has an interest in keeping the business.' When China tightened its grip on mining, Russia invited operators to set up in Leningrad. The race for money acted as a firewall.

The other flank was the nature of the currency itself. Against those who saw it as a house of cards, the monetary thesis stood firm: 'Bitcoin has only one utility, to serve as money, and it does it better than any other because it is not manipulable.' Its only acknowledged drawback, volatility, was expected to decrease with time and adoption.

What If It's Just a Screen?

The fundamental doubt no one dispelled. Whoever has bitcoin stored in a cold wallet doesn't have money: they have arrogance and numbers on a screen, as one of the oldest put it. For its value to be real, someone has to sell it and exchange it for something tangible. And whoever buys high only expects to sell it for more to someone who comes after. The wheel turns as long as new people join.

The same could be said of traditional economics, defenders retorted: a company's value also rests on expectation. The difference, critics insisted, is that behind a stock there are factories, patents, and profits, and behind a bitcoin there is a line of code replicable infinitely.

The debate ends there. With the currency soaring and the fork in tatters, the question that remained floating—where exactly does the money that bitcoin holders believe they have come from?—remains unanswered. No one knows if they are rich or just rich on screen.
