The only coins am looking to invest in now is the Bitcoin and ethereum. I missed buying bitcoin when it dumped below $3k, now it's above $6k.. These two are sure coins for long term investment. Nothing like short term for me.
Many people say like you, they regret not buying when it's cheap, I suggest buying bitcoin now because the end of the year reaches at least $ 15,000, I hope you won't say that twice later.
