I got into the bitcoin again last year after losing all my 4.5 bitcoins to ponzi schemes early last year. I bought in bitcoin again at $20k. Now bitcoin is $6k+. I'm regretting my actions.

Sorry to say but I don't know what kind of fool you are dude.after losing 4.5 bitcoin in ponzi still you didn't learn how to value your hard earned money?and for what i am thinking you have lots of time to buy since you have lost early last year ,why needed to be on the highest value bitcoin ever has?theres a time when you can purchase in October or in January
It is very humane if you feel sorry, but it's all because of your carelessness, I think you are too hasty to invest, you don't analyze it first so you experience a lot of losses, my advice is to do the purchase of Bitcoin now, because this coin will probably go up, but all decisions remain in your hands.
That kind of thing you have to go through if you are a trader because the virtual world is full of question marks with prices going up or down.
