Most of the regular people in my area thinking bitcoin to be a scam because they so caution with online currency. i've try to explain to people in my area but they still not believe to bitcoin.
i suppose you, i also will explain that bitcoin is save from any scam if we becomes smart bitcoin user. But if they can't trust what I said , i perforce ignore them. :/ .
If you tried to convince them with that shitty English no wonder they didn't trust you. Bitcoin is not safe from any scam, it's in fact quite easy to scam using bitcoins, easier than fiat right now because most companies/business using bitcoin have no credentials or give you any security and because bitcoins transactions are not reversible you have pretty big chances of getting scammed.
