This ought to make you feel better . . .

If I had spent the cash that I used to buy mining equipment to instead buy bitcoins, I would be sitting on roughly $3,000,000.   Instead I have a teeny tiny fraction of that.   I don't really regret my decision, as it fit my risk analysis, but hindsight does suck, a lot.

I hope you managed to hang onto some of your stash.   If you did, you will still do quite well, and one day will be able to leave that job behind to focus on more important things.
