Your dilemma that you are dealing with right now is exactly how bubbles happen, so I hope you can remember it as a useful exercise with investing. Altcoins are a bubble within a bubble - Cryptocurrencies are a bubble, but altcoins are like a super bubble (which seem to be correcting a bit now at least). I can't help you with this. There is much more money to be made in altcoins, that I won't hide from you. There is also far more money to be lost. Nothing will teach you this but experience. I hope you don't ever gain it though!
