Does anyone know how many people is using bitcoin very often and how many are "weekends" users, with weekend users I meant people who bought it and hold it for a long time 
i think it's very hard to tell how many people using bitcoin bitcoin very often and people using bitcoin on the weekends every people have their reason and different reasons, to hold or to trade their bitcoin
and i think who's using bitcoin very often is day trader, and who's using bitcoin in the weekend is miner to pay electricity but dunno the exact number people using it
you can create survey, to know that
