That's not really true, a lot of us more sensible people want to 'cash out' a little slowly as the price goes up, and what better way to cash out than actually spending the bitcoin on an actual product and supporting the economy? I'd be willing to bet that as people suddenly find themselves with tens or hundreds of bitcoins, and that they can buy a pizza for 0.05 BTC, they are quite open to the idea of receiving what is essentially free pizza. Sure, that pizza could be worth five pizzas tomorrow but you still have a decent chunk in bitcoins and if the whole thing plummets to earth then at least you got something delicious.

Hilariously this post highlights like, every reason why trading goods for BTC is a sucker's deal for the retailer.

How? The retailer gets exactly what they would if they had just asked for local currency, except maybe a little extra business.

My point was rather meta, but it was the choice of language. "Pizza effectively for free" - lots of things about Bitcoin seem to involve people hoping they get something effectively for free.

In the case of the price volatility for hoarding bitcoin while it rises, it underscores the deflationary nature of the currency - no economic value has been contributed by someone holding the BTC, but they've gotten richer regardless. Sitting around doing nothing with the BTC did not produce any economically valuable activity - it wasn't invested or used to finance starting that pizza place, for instance.

exactly my sentiments.
