21 million coins is not enough to serve a country talkless of becoming world currency, I think we should start using Satoshi count more than the word Bitcoin. We also need fiat especially for the non-tech people
We will start using Satoshi more for units when the price of bitcoin sky rockets. But right now, we're far from that. We're still using the usual 0.00x
BTC. There are some that use x mBTC but most of the time it just creates confusion because not everyone knows that m stand for micro which means x 10^-3.
Today, we use the unit satoshi for dump coins. For example, 1 satoshi each. We also use the satoshi units to refer to the price of other altcoins. For example, ICONOMI has the price 40k sats. Simply because it's much easier that way.
