Any sharp movement in the crypto-currency market is a combination of a large number of factors. Not a lot, - Elon Musk, not a lot, - a fall in American indices, and of course - a simple human panic. Time will pass - prices will recover, but this "lesson" of a good fall in prices will cool the heads of many and teach them to be more careful about the crypto market.
I know the market will recover but it is really important to get an idea of what caused such a rampage within days. I was watching all this and we friends at telegram were distraught because these things earlier only used to happen when the market was small and a single whale could manipulate but this happening in 2021 shocked us all.
China Banking Association warned member banks of risks associated with digital currencies. Other digital currencies suffered sharp declines as well and the dump wasn't on btc alone even ethereum dumped to $2k.
Ethereum and other coins are just dependent on the bitcoin market because if BTC is crashing you would always see every coin dropping almost by the same margin if not more. This also shows the domination of BTC in the market though.
I think like always we will never be able to find what actually caused this rampage and who was behind it. These things actually bring a lack of trust and safety in our already volatile market.
