Bitcoin has died in the headlines dozens of times, and every time it has come back — usually to a new record high, and usually just before collapsing again. Since it first attracted real money in the early 2010s, the cryptocurrency has traced one of the most violent price histories of any widely traded asset: repeated cycles of euphoric booms followed by punishing crashes, each one drawing in a fresh wave of believers convinced this time was different.

Understanding those cycles is less a lesson about cryptocurrency than a lesson about human behavior under the influence of a rising price — and about why how much you own matters more than whether you are “right.”

Three manias, three crashes

The pattern has repeated with an almost rhythmic quality, roughly every four years. In 2013, Bitcoin climbed from a few dollars into the hundreds and then past $1,000 for the first time, before collapsing over the following year into a long, demoralizing bear market. In 2017 came a far larger mania: a retail frenzy drove the price toward $20,000 amid a wave of initial coin offerings, only for it to lose the great majority of its value through 2018.

Then, in 2021, a boom fueled by institutional interest, stimulus-era speculation, and a stampede into related tokens pushed Bitcoin to a high in the neighborhood of $69,000. The following year brought another deep bear market, compounded by the implosion of overleveraged crypto lenders and the collapse of the FTX exchange, which wiped out fortunes and shook confidence across the industry.

Each cycle told a new story about why the price would keep climbing. Every cycle ended the same way — with a crash that erased most of the gains.

The halving narrative

Much of the folklore around these cycles centers on the “halving.” Bitcoin’s software is designed to cut the rate at which new coins are created roughly every four years, tightening the pace of new supply on a fixed schedule. Enthusiasts point out that past halvings have tended to be followed by major bull runs, and treat the event as a kind of scheduled catalyst.

It is worth being careful here. A handful of cycles is a very small sample, and correlation is not proof of cause. Prices are driven by many forces at once — interest rates, speculation, regulation, and sentiment — and the halving narrative is at least partly a story people tell to justify a rally already under way. The honest summary is that the supply schedule is real and predictable; its precise effect on price is not.

Volatility as the defining feature

Whatever drives it, Bitcoin’s defining trait is extreme volatility. Drawdowns of 50%, 70%, even 80% from a peak have happened more than once. An asset that can double in a few months can also halve in a few weeks. This is not a malfunction; it is the nature of a young, speculative, sentiment-driven market where there is no earnings stream or cash flow to anchor a “fair” value.

That volatility is exactly why the hype is so dangerous. The stories are loudest near the top, when the price has already run and newcomers feel the sharpest fear of missing out. Buying into that noise — often with borrowed money or an outsized share of one’s savings — is how the largest losses get made.

The lasting lesson: position sizing

The durable takeaway from Bitcoin’s history is not a prediction about where the price goes next. It is a lesson about how much of a volatile, unpredictable asset a person should hold in the first place.

Bitcoin may or may not have a long future; reasonable people disagree. But its price history is an unambiguous tutorial in one thing that never changes: your exposure to an asset, not your conviction about it, is what determines whether a crash is a setback or a catastrophe.
