Serious question - so if a Bitcoin is worth around $10,000 today - can you then ( I assume) get paid in part Bitcoin ie a % of that one bitcoin to enable purchases of say just a few hundred pounds / Dollars / Baht etc ? And assuming that of course HAS to be the case is there a name then for that smaller part of a bitcoin or is it simply "I'll pay you .0003% of a bitcoin ? As I said - a serious question.
