but anyway back to bitcoin.. a few years ago there was bitcents (0.01btc) but that very quickly became redundant and no longer used when the price of a whole btc went to $100 a coin..
people got confused pretty quickly that a bitcent was $1.. and now a bitcent (if people still talked about it) would be $4.. so confusing to try linking bitcoin to dollar measures.. and confusing to have all the temporary measures in the middle, rather than thinking long term (which isnt that long at all)
