Since you already experience investing in alts (but it didnt turn out well) you're already aware on what to expect. Do you think its worth it to invest in alts? In my experience, investing in alts are profitable however there's a timing on when to take profit so if you're not patient to wait then it might not work.

You're the only one who can decide for yourself, because for me even alts are not doing well I prefer to not go all in with btc and consider diversifying.
