As a former derivatives and commodities trader, Matthew Dibb is always expecting the unexpected, but the crypto market is a whole new ball game. On Tuesday, right before major cryptocurrencies whipsawed amid El Salvador's official recognition of bitcoin as legal tender, Dibb, who is based in Singapore, went to bed at 11 p.m. local time. "Then I got a call only 45 minutes later saying the market is getting crushed," he recalled in an interview. "So I got up and I was up basically the whole night." Dibb is no stranger to volatility spikes in crypto.
