Are you investing your money on Bitcoin?
Do you use Bitcoin to buy things in internet?
You earn money with Bitcoin?
Mostly all three. Yes I invest money on bitcoin every now and then for little trading and buying things with bitcoin is very common for me. As for earning money it's the same thing from trading.
yeah I think most users of bitcoin have been using bitcoin to those three things, or even have the goal of those three things, but I'm sure that most often are they using bitcoin to earn money or investments, rarely or only a few people are using bitcoin as their currency?
