This is one reason bitcoin might fail and probably the only one weakness of bitcoin.
The stupidity of some bag holders who see bitcoin as only an investment you need to hold forever.
If the Lazlo would not have bought that pizza there is the possibility nobody would have used bitcoin for a trade.
And guess what would the value of a coin be at this point if everyone would have just hodl.
A big fat 0.
With nobody spending bitcoin there would be no shops accepting bitcoin, there would be only a few exchanges for miners to sell 1000 coins a day and that would be all, no services accepting bitcoin, no projects no nothing. And the value of your hard hold coins would plummet to the ground. Who needs something you can't use?
