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? Shocked :I downfall still possible? For example Metahero
With the price of bitcoin going back to 19k and sliding even below, downfall is definitely possible - but this is a price and not a project's downfall.
Specifically giving statement is not possible because every project is unique and prices dont necessarily indicate the current development status of any project. For altcoins, if you have faith in a coin, do invest in it at the low price, but the faith in important.
For bitcoin I am expecting further crash and therefore my suggestion is to put a hold on the buying for sometime and observe the market for further movements. Day trading should be stopped by any newbie at this point.
