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.

Wow, sorry to hear that dude, but I think Bitcoin will raise again, but probably need a while to back to 20K, but blockchain is always full of surprises, you will never know right?
