If BTC loses 92k daily, it goes to 84k or below, some altcoins will melt 80% or more and enter bear market... but I think BTC will go up and that this is now the bottom.

The market is manipulated by whales, institutional investors and those who spread panic by saying that the Bull Market is over and that the Bear Market is about to begin.
The Market will rise again. Only those who sell their cryptocurrencies in the face of these traps will lose money. Don't be stupid, hold on to your cryptocurrencies, unless you want to enrich the manipulators.
