Crypto Winter

The term borrows its imagery from the "AI winter" concept in computer science: a season where enthusiasm freezes, funding dries up, and only the most committed builders keep working. In crypto, it describes a downturn that goes beyond a normal price correction, touching venture funding, hiring, and public sentiment for well over a year rather than a few weeks or months.

Unlike a bear market, which analysts can define with a hard number (typically a 20% drop from recent highs), a crypto winter has no single trigger for when it starts or ends. It is judged instead by the mood of the industry: exchanges cutting staff, startups shutting down, venture capital pulling back, and retail traders leaving the market altogether.

The most severe example ran from late 2021 into 2023, when Bitcoin fell from its then-record high of roughly $69,000 to around $15,000, erasing roughly $2 trillion in combined market value. The collapse of the TerraUSD stablecoin and its sister token LUNA in May 2022, followed by the bankruptcy of hedge fund Three Arrows Capital and the exchange FTX that November, turned a routine downturn into a chain reaction of failures across lending desks and trading firms.

Earlier winters followed the 2014 Mt. Gox hack and the collapse of the 2017 ICO bubble in 2018. Each cycle eventually gave way to renewed growth, which is why long-term holders often treat a crypto winter as a stress test rather than a permanent state, though there is no guarantee any given downturn will end the same way.
