The same as it should feel if you spend your fiat on something other than bitcoins before the price goes up.
When people hear about Lazlo spending 10,000 bitcoins on a pizza back in 2010 they usually say "damn, he's probably kicking himself right now".
Well, why aren't you kicking yourself right now for not buying 10,000 bitcoins for $25 back then? It's the same thing. He could have spent $25 on a pizza or 10,000 bitcoins on a pizza. Or he could have spent $25 on 10,000 bitcoins.
So if you spend some bitcoins on something, then the price goes up. Don't worry about it. Would you have spent fiat on that thing? Fiat that could have been used to buy bitcoins...
very true Elwar.
if i could travel back in time i would spent 20.000
BTC for some fucking pizzas. people that say "damn, he's probably kicking himself right now" dont get it.
Obviously everyone kicks themself after doing something like that, but no one knows the future, and you could have just as easily saved yourself from LOSING a lot too.
BUT, the one thing I've picked up following the show "Shark Tank" and the investors on the show is they have one common lesson: Failing is good. You need to LEARN from your failures so you don't make them again, and you will be better equipped going forward to succeed. There's no point wasting time being upset because you made a bad call, nothing you can do to change that. Just move forward and keep going.
