The fact is people around me doesn't know what bitcoin is.
Even well experienced and educated teacher also don't know what bitcoin is
and when they hear about it they think that is useless and so they don't care about it.
And also when I gave them the idea what is bitcoin, they were enlightened that this kind of currency is not illegal
like other knows, then now thay want too to make this kind of money in their wallet.
in fact many people outside already heard what bitcoin, may they hear on television or on the internet, but I do not know why they do not use bitcoin? maybe they're not too concerned with new technology
