How do you run an economy on a deflationary currency? If someone want's to start a business there is next to no point in me lending them bitcoin in the hopes of getting it back with interest. My bitcoin would increase in value regardless. >Bitcoin will reach a value high enough that more and more people will start accepting it alongside fiat. It has value now yet it isn't being accepted by many places. If amazon adopts it i'll change my view here. For now it's just a commodity to me.
