I think maybe the real question is... who is selling and why? I'm sure not selling, but I have a theory why EVERY SINGLE CRYPTO is going down at the same time, and it's not because everybody is selling, it's market manipulation. I think it's the bankers/elite/government, they have lots of money they probably have Chinese people buying all the cryptos in small amounts over time at a certain price, then they tell them to sell them all at the same time, lowering the price, effectively destroying confidence in the market.
or it's just people being stupid
