Just believe and never stop believing that bitcoin will come back again. You are not alone in that situation and best thing to do for now is HODL your bitcoin as much as you can. Better days are coming man and bitcoin is starting to recover now.
That would have been a perfect idea without the concerns and the worries for the repayment of the loan. To that effect, just hodling and believing Bitcoin would recover soon enough, obviously tends not much comfort for his frayed nerves. He simply needs other source of income to be able to hodl those 3 Bitcoins to profit again.
Patience is the key idea here and the recovery of the loss will take place eventually, I'm pretty sure about this.
Just wait patiently and see the result at the end.
