Bitcoin's $19 billion wake-up call: One-year after flash crash, has crypto learned anything?

The October 2025 crypto crash exposed the dangers of leverage and crowded bets. A year later, analysts say those risks remain. Nearly a year after one of crypto's most violent selloffs, the question hanging over the market is whether traders have learned enough to prevent another one. Just days after hitting a record high above $126,000O, on October 10, 2025, bitcoin BTC $83,696.96 plunged from around $122,000 to $105,000, with much of the decline occurring within minutes. The crash triggered roughly $19 billion in liquidations across crypto markets, catching traders off guard after months of bets on further gains.
