The maximum numbers of bitcoin to be mined is 21 million bitcoins. Bitcoin can not be used as money by the whole world because it has a maximum cap. My opinion . What is your stand ?
To me, the cap is a moot point and was just made to point out that even if this is a digital currency that this would still be running on limits that are alike what we deem and limit the paper currency to exist and operate. The limit is much more for its safety and more to the goal that bitcoin or the cruptocurrency market is not a currency that a person or a group of people can tinker and replicate an i inite number of cryptocurrency would have.
