define many people, because you guys are always talking about your acquaintances, that it is only an inner circle of people, they don't represent many at all
and do not confuse "didn't hear" with didn't knowing how it work, because this is what i get from the "first a lot explanation is needed."
because there are many out there that did hear about bitcoin, but they do not have the faintest idea what it is
You live in a country where everyone else aware at bitcoin. You dont leave in the country where the majority of people dont know about this thing. You cant ask many people about bitcoin just to make sure if the entire country know it but you can take a sample of some people and asked them and that is what I am doing and most people dont know/never heard about it.
