So OP, it's not all altcoins are bad for investment, and I started with both altcoins and Bitcoin, it's less fun for me if I can't figure out why one is better than the rest.
First I did crypto trading to accumulate more Bitcoin. I use BTC altcoin pairs to do that. I think I succeeded, I was able to earn more BTC and help me in financial matters.
There are standards of bad altcoin categories that should be equated. So if we lead to profits, then we can use bad category altcoins to make profits. But there is a note that there may have to be noted, don't hold back for long it is better to enter the profit and leave. We only take advantage of the moment, not the quality of the coin or token.
