Why did the crypto market crash?

[Apower$]

“I think it's plausible [it is causing volatility] since it's the largest ever options expiry [for Ethereum],” Ki Young Ju, CEO of CryptoQuant, which provides data for investors, told Decrypt yesterday. So, where to next? Singaporean crypto investment firm QCP Capital predicted today that Bitcoin would soon reverse to $39,400, and that ETH would return to highs of $2,550. Deribit’s Bitcoin futures market is less optimistic, and traders there concur that Bitcoin should return to just $33,220 by this time next year.source
