So, why do we need to use Bitcoin???
It's not that you must need to use them for some people it's just easier for them
to pay online and do other payments. You don't need to only if you want to .
Yeah you are not forced to use Bitcoins if you not want to, so you do not need to use Bitcoin. I use Bitcoin because I want to use it and want to make money.
Nobody forced me to use it.
Exactly none will be forced to use bitcoin. Important thing in bitcoin usage is the proper knowledge, if used without proper knowledge will stop the user not to use bitcoin anymore. Only after days bitcoin accessing seems to be easier.
