My wife always says that growing up, all her dad and brother used to talk about at the dinner table was "I should've invested in that stock when it was cheaper!" or "I should've sold when it was higher!"

I feel that way about Bitcoin/others. It's always regret all the way. It's like buying a stock.

I had a chance to mine lots of bitcoins in 2011... never got around to doing it. It's now the same as "I should've bought Apple stock the day before the rumored iPhone debuted, like I told friends to do"
