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. 
Yes, that so hurt, that's why before we join in investment we must learn it, dont join only because profits, we also must learn about lossAbout bitcoin last years at $20K, just wait, i think this years bitcoin will break new high price then you can sell it
Also you can keep hold it for benefits in the future
