I Think first You need to made right choice and i hope you will get benefit from your holding coin and trading business.
Sounds a solid plan, but I'm just wondering why did you just emphasize the mistake in 2021? I mean you're here long enough before the pump in 2017 which really caused a lot of investors to regret. Haven't you learned a lesson from there?
You should have made good decisions in 2018 and buy more Btc or alts that has potential to grow from there.
It's just Ironic that you're here for quite a long time yet you haven't decided to make any investment plan but just now.
Savings and Investment plan is a must and mistakes is one of the best teacher on improving out yourself on dealing with these things because if not then you would really be finding a big problem.
