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.
Today Bitcoin has reached $10,000 and it is a very good sign for investors to return to this market because after reaching this price, the top coins are having a huge increase in prices. I think the market has now entered the uptrend stage but it is completely different from 2017 so it is better to choose the best projects to invest or the coins that are in the top 10 CMC. In my opinion, Bitcoin will still raise prices even further and later this year Bitcoin will soon reach $15,000
