Altcoins are worse than penny stocks by their centralization and premined coins or thin-air minted coins or tokens. They are too easily for creation so founders and core developer team can easily abandon their projects and create new ones. This basic trait of altcoins makes them are very sensitive to die anytime.
Top altcoins are like penny stocks but non-top altcoins are like dead coins, and it's only matter of time when shitcoins die.
Yeah, penny stocks are pretty terrible too, so I am not sure which one is true, but yeah alts are terrible. So many tokens with terrible centralization, made up tokens, worthelss rewards and many other bad results. We should focus on how to make money and that is not a way of doing it, you should focus on making money only based on how to get a better result by investing into something better.
We can't make this work, it's just not possible and for that reason we should not be getting a bad deal out of this. If you do, then you are going to get a greater return, and would be focusing on how we can make some income from it. If we invest top ranked ones, then alts are good too, but if you invest int smaller and newer ones, they are terrible.
