Bitcoin is based on an increased demand an a deflationary supply, however that eventually leads to a coin that people don´t use to trade or to transact. What do you think that the emission rate of a crypto should be to be used as a coin? Any automatic mechanism to adapt exists?
As form of profit yes, deflation is very good for a coin. Look at Bitcoin, with its deflationary feature, bitcoin is expected to increase in value overtime. This will give investors to hold bitcoin and reap reward in the future. I am a fan of this kind of system, the longer we hold it the larger its value, thus it can make the market demands for it more. Early comers which support the coin first will have more benefits since it is just because they had jump to the economy when no one is believing it (confronting Risk and beating it).
