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.

You didn't learn from your first experience after losing your 4.5 BTC to Ponzi scheme then you bought bitcoin at the price of $20k bad decision now you have to face the consequences of big mistakes that you have made.
