It may not help much, but remember that it was the rational decision at the time. There is really no reason (other than hype) for the value of Bitcoin to move the way it does.

If you don't play the lottery and the numbers that you would have picked win big, then not playing the lottery was still the rational thing to do at the time, because the chances of winning are so astronomically slim.

My brother decided that Bitcoin was likely to steadily increase in value (in the long term) and spent about a thousand bucks to buy three of 'em. Then he got hit with some surprise money trouble and had to liquidate, losing about a third of his investment.

He was not amused when BTC became an investment hype.

I upgraded my PC with my Bitcoin. Making $800 off a $20 investment was a great deal IMO.

I wish I'd forgotten to check on it...

I discovered I sold my old PC with the HDD with mined BTC when compusa announced you could buy components with bitcoins, but tbh I think I would have used all of them when their value was still very low
