Crypto volatility: definition, examples and strategies to tame it

The roller coaster, by subscription. Volatility is the first thing a newcomer to the crypto market discovers, often to their cost, sometimes to their delight. We curse it downwards, we praise it upwards, even though it is the same phenomenon, this crypto volatility which is all the interest and all the danger of this asset class. It is time to define it properly, with supporting figures.

Volatility, definition of an amplitude that does everything

Volatility measures the amplitude of variations of an asset over a given period, regardless of their direction. An asset that gains or loses 5% per day is volatile, an asset that moves 0.2% is not, period. Professionals quantify it with the standard deviation of returns or, on a chart, with tools like the ATR (Average True Range), which translates the average width of the candles into points.

Why does crypto have so many? A market open 24 hours a day, 7 days a week, a lower book depth than for stocks, an investor base very sensitive to emotions and a mountain of leverage on top of that. Shake everything. You get double-digit days that stock markets only experience in the middle of a crisis, and that crypto volatility serves several times a year, bull market included.

August 5, 2024: when the yen caused bitcoin to plunge by 15%

The perfect textbook case, because it owes nothing to crypto. At the end of July 2024, the Bank of Japan raises its rates, the yen jumps, and years of carry trade (borrowing in yen at almost zero interest to invest elsewhere) unravel in panic. On August 5, the Nikkei collapsed by 12%, its worst session since 1987. Carried away by the shock wave, bitcoin fell by around 15% towards $50,000 and ether dropped 22%, its worst day since 2021, with more than a billion dollars in positions liquidated, as CoinDesk reported that day.

No crypto bankruptcies, no hacks, no sector news. Just the plumbing of global finance unblocking in Tokyo and taking your wallet right into your pocket. Crypto volatility is not only an internal affair, it also amplifies shocks from elsewhere, because risky assets sell off in blocks on stormy days. This sets the record straight.

Taming volatility when you are a private trader

Volatility is neither good nor bad, it is the price of the ticket. Without it, no double-digit returns, but with it, nerve-testing drawdowns. The only variable under your control is exposure. Positions sized to survive a day at minus 15%, cash set aside for sales, and stops designed according to the real amplitude of the market rather than placed haphazardly.
