I think in trading it is more profitable when the volume is high. [/bBecause the coin is active therefore it goes up and down. So If you notice it you just buy low and sell high in a short period of time. And you get profit or double your money in the future.
Not only that, a coin must also be traded on multiple high level exchanges. I was going to invest in ETC, my first altcoin but I decided not to at the last minute. A big mistake. A few months later now it rose x5.
ETC was a good example of a buy low, sell high investment.
