Some very good coins out there have lost 95% of their value already is it possible to see more down fall? I'm throwing this to those that are present in last bear market, marketcap and volume is over millions of dollars and price is 95% down?

:I downfall still possible? For example Metahero.
Easily. Most of these coins will literally stop trading and go to zero. They were literally made to just make profits for people and aren't needed in the market. People will just move on. Big drops still incoming.
Some altcoins and shitcoins are know for giving massive profits when the market is green. They can do x10, x20 as the case may be. But one notable thing is that during the bear, they also make -20 and more. A season like this shakes many projects off the market and only few lucky ones and the ones that has good road map and usability survive the blood bathe.
Meanwhile, the King hasn't gotten any strong support, so there is possible downfall, you never can tell. So, invest only what you can afford to lose or keep for a very long time.
