I think this is the influence of traders who have begun to understand what coins have the potential to rise and what coins have no potential, many new coins that do not have a good development that make the price not too good even a very low trading volume indicates that the coin project failed.
I agree if this happens to shit coins, which only make shrubs on the Exchange. In the end the price of the shit coin will disappear and die on the Exchange. Therefore choose the Altcoin Potential that has a lot of volume and users. Don't choose shit coins / tokens which the price is always destroyed in the market.
You guys must realize the fact even not all of the major altcoins will always bring us to the profit. Look at some coins like zilliqa and it's brought the late investor to the bottom price and lose a lot of money easily.
It's a good idea to choose a good altcoin with huge volumes and popularity but some times it's not always useful at all consider the price will be determined from what's the usefulness of the product and does it really useful for us?
