With the increase in bitcoin price, I think we should seriously consider using mBTC?
For example, if I am buying a $5 coffee, it will cost 0.0033 BTC now... Too many zeros behind the dot! Isn't it better if we use 3.3mBTC for a coffee? At least this is easier for someone with poor math like me...
Why are you thinking about this and considers this as a problem? It's up to you if you are going to seriously consider using the measurement of bitcoin as satoshi, mBTC or zeros digits and bitcoin. But for me it's easy to use the unit of "bitcoin", 0.1 bitcoin and it's up to you on where you are convenient using any unit as long as it is bitcoin.
