I do notice that some people naturally don’t allow bitcoin in any of their daily transactions even when it faster and easier, they still don’t prefer using it, I have noticed this a lot, Some classes of human,Sometimes when they are to receive money from another country like international transfer sometimes it takes 2 3 days to arrive,They will advise them to use bitcoin and they still don’t accept it even it faster and easier. Now how come we make bitcoin come to people.
They don't use it because they aren't familiar with blockchain, or maybe it looks too complicated for them. And there old fashion people, they do the thing they used to. Habits doesn't change in a day.
