With the prices down at least 80% of its value right everything can be considered as a hidden gem in the crypto market. So if I were you I wouldn't be choosy when it comes to picking up any crypto I would see right now. The only thing I should consider is if this crypto I am buying is a known mover at the same time BTC is rising up, becUse sometimes there are some coins like DOGE left in the action during big price jumps.
If a project is down by that much then its a bad project to invest to, after all 80% is almost at a 100 that means 80% of the project is just a waste. Just gotta pick up the pace of those projects to catch up to those pumping and having a bullish time.
