Most of the alts from the previous Bull run are actually ZERO now. They haven't worked for months/years and now their coin won't be having any value unless they do something. Investing in altcoins is a risky business, especially those who are below the top 100 on coinmarketcap or don't have a proper community. I would suggest that if you are in a profit then exit and keep your principle mainly in USDT or BTC.
