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?
It's a 50-50 thing and I like to fancy my chances on that, especially if there is utility and the price is low at the time of wanting to buy in. In the case of the sample token, Zclassic, I think it's a great buy. Even though it's currently trading at less than $0.35. You have to remember that it once did $230 at ATH in 2018 and may repeat such feat during another bull run. By the way, that token is even a fork of Zcash which is also not doing badly in the market ATM.
If any investment had to consider this coin on the longterm and does not check the ATH price and present price in the market, community and exchanges, research the roadmap and how well the team is committing to the project he might wake up one day and all the coin delisted from all the exchanges, which could mean a big loss. Some coins are spending the last lap in this cycle and will be gone by the next bear.
How many buyers want to spend that time to do this thorough research before buying. Most buyers are impatient going through all that rigors. They just want to trigger a trade and be done with it.
