My mistake is getting into bitcoins in the first place.
Over the past couple of years I've invested and built a small mining farm. Overall I made some profit, just a few hundred dollars.
But to think about all the time and effort I spent doing all of that just for a few hundred dollars... It's almost a waste of time!
If you feel that your mistake was getting into bitcoins in the first place, then why are you still here ?
I think that you shouldn't look at it only profit wise. Sure, you made a financial error, but that doesn't mean your next move is going to be bad one as well.
I suggest you re-asses your moves, and don't give up on bitcoin as a whole, judging by a single error you made.
