We regret about missing Bitcoin, then about XRP then about Ethereum then Doge then Shiba then Pepe (these are some top of my head and from what I've come across in my crypto term).
Point being there are always new opportunities and dwelling on regrets is futile.
you shouldn't regret things that shouldn't be regretted because it's all out of your control, now i ask, if you regret it now then will you immediately know what crypto assets will be pumped again in the future? of course not..right
the pumping that occurs in dogecoin, shiba inu and pepe is purely the result of speculation and it is so different from the pumping that occurs in bitcoin that you cannot include it in the comparison list.
what you should be doing right now is continuing to hone your analytical and technical skills in your trading, or you can also try joining a signal pumping group
(not so i suggest), basically just do what you can do right now to try to read the token opportunities that will be pumping in the future rather than regretting the past.
