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.
Beside self pump binance coin I don't see any worthy known coin that's pump 30-50%. I must of missed something.
Precisely because of the time when you are losing faith in altcoin, when the shark is gathering it. Everyone's mistake is to pay attention to when the market rises to buy in and lose money without thinking about when the market is gloomy to buy. When bitcoin is priced at 3k $, I think no one dares to buy it but when it is 9k $, it is massively bought?
