As probably you know more than I do about BTC:
- is it a real limit
- is it a good thing? I think it is but it looks like BTC will become more a commodity and not just a payment system
It is a real limit ,but i am not sure why Satoshi came up with the number of 21 million as the limit,either way that is the limit,with the price of bitcoin rising very fast,it cannot be used as a regular payment system because of the higher transaction fees and hence we can consider it as a store of value.
