I have written some axioms that are widespread in trading platforms Which relates about currencies exactly:
4. Volume is low and the price is low?
this coin is dead , dont buy it .
simple but i hope i helped ,good luck
Maybe number 4 not all coins are like that, I add one more possibility besides death ..
"Many holders persist not to sell these coins"So, there are not many coins in the market
Investors don't like to buy or hold any coin doesn't have any significant number of the trading volume. The 24-hour trading volume shows how many people like that project so it is very important. Its true low volume doesn't mark a project as dead but it identifies a low-quality project. If that project has a low volume for a long time that means its lack of investor's interest.
