One of the phenomenal stories that proves that Bitcoin / Cryptocurrency CANNOT or is not suitable to be used as a currency for a medium of exchange or payment is the story of someone who once bought a baking dish with a Bitcoin of 10000 BTC. If only that person, using 10000 BTC at the moment, is not just the Pizza he will get, the Pizza company is all he can buy.
So? Still thinking about Bitcoin as money? Still like to promote Bitcoin as an alternative currency and drive other people to buy this using Bitcoin?
