a lot of people use bitcoin to transfer wealth across borders cheaper and quicker than banks, what category would they fit in?
Personal the only future uses I see for bitcoin is 'Speculator' where bitcoins is a store of wealth, massive market. And money transfer, also massive market.
There's a whole other category of people that are using BTC to solve practical problems (store of value, value transfer, purchasing gray market goods and services, etc). I don't consider them to be "Bitcoiners." A Bitcoiner = passionate bitcoin believer.
