Bitcoin, in many occasions, is deemed as a currency, which I believe will inevitably become a super-sovereign currency and world currency supporting the entire human civilization. So, what is the nature of currency? Why can Bitcoin become a currency?
One of the properties of bitcoin that is very likely to be a currency for the future, because bitcoin can not be counterfeited like fiat currency basically, if a currency can be counterfeited then the supply will increase which can cause a decrease in price, just like bitcoin, bitcoin runs in technology blockchain and blockchain systems are certainly hack-resistant as every transaction has to be verified by the miners.
