Can a coin with very low 24hrs volume still brings profit? For example zclassic, the volume isn't even up to 20k in 24hrs, is it worth the risk or it's a big no for you? What do you think about this?
if it is for long-term investment, then of course investing in coin that have a low volume can be profitable in the future, ...
You should try to avoid such coins for long term hold. Fro short term day trade is totally fine but for long term you will get burned. Right now we are in bull market and volume of all coins is x100. So when bear market start if a coin have $100k daily trading volume it will have $1k when bear market start. And you will simply not be able to sell them at all.
