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.
:I downfall still possible? For example Metahero.Unfortunately it's possible for any altcoin like what you have mentioned. There are no guarantees or astronomical guaranteed returns for any cryptocurrency (except stablecoins unless de-pegged like Terra Luna's UST) that are subject to market volatility. It can go up or down anytime without warning, because it is unpredictable.
Even if you are so good in technical analysis, reading charts, predictions or so, the only master is the market itself and has the final say in the end.
