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!
You are not the only one that got burned by investing into mining. By the nature of Bitcoin mining, investing into it is a highly risky and I don't know why are people still doing it. You are almost guaranteed to lose money except if you don't live in the place where electricity is very, very cheap.
I am sorry for your loss, but I never understood people that were getting into Bitcoin mining.
