Dude that's what we call logic. I know it seems hard is crypto to talk about logic but it's actually something useful that exists for a reason :p
All coins got historical profits in the last month.
Overall the marketcap was terrifyingly high. Every day was a new all time high.
Do you think it can continue like this forever? Of course at one point the price is going to fall back... That's just plain logic.
The rise was too fast, too high and without enough logical reason. Hence the panic and the dump.
