Majority of this was due to fucktard rich traders on Binance that uses margin account to tip smaller cryptos and leaves the balance over so binance terminates the account and liquidates the holdings, almost every coin went down that night, was watching them, also coinbase bots couldn't keep up regulating the price, for around 20 mins it was floating up and down by around 1.5k -2k and over by moments, the crash as well was a good opportunity for some sharks, if you are able to keep up trading at that speed or have a bot well configured, in a bunch of minutes you could have made an exponential growth with a good investment
