Stonks don't depend on another person buying an asset from me. It depends on the value the underlying business provides to customers over time.
Bitcoin has a unique value proposition in that it can transfer and clear huge sums of for a low price and rather quick. This feature is only useful on occasion, to a limited number of players. For everything else, there's Mastercard ;)
I don't take issue with BTC. Raul's description of it rubs me the wrong way.
