Altcoins are basically alternate coins.. most of them will crash and burn.
If you choose the right altcoin, and you had bought thousands of those.
Who knows? No one can predict what will happen in the future anyway.
I totally agree with you.
Moreover I add: the secret is diversify your portfolio of altcoins and investments...

Yes, I am supporting that opinion too, if you would have many many tokens on your wallet, so definitely at least one or two of them would grow, and you would have your profit from them.
