It can also go the other way - I regret investing in dozens of altcoins that collapsed to 0.
Exactly, there are thousands of Altcoins in the crypto market, and investing in them is just a total waste of time, and the only few that have managed to make names for themselves are usually the ones that are being used as examples or as reasons for opportunities that one has missed to invest in other Altcoins. There is a possibility that some coins can do a +100% or 1000% in a few years, but the question is, do you know which one it would be? is not about putting hope and your money in one token that cannot even turn shitcoins before 12 months are fully over. Someone said that Altcoins are just a "try your luck investment."
