Just because of you're losing your faith on altcoins doesn't mean that other people are the same. Infact, market showed many positive signs. I saw a lot of 30-50% pumps in the last few weeks when bitcoin recovered from $7000 to $8000. No one can tell you how long it's gonna take. It's just whether you can keep your patient or not. If you buy your alts when bitcoin was at $19k, I think it'll be long.
