Be careful as the Bangladeshi government has banned bitcoin. But what if the person you have taught is the one that will report you to the authorities?
Just a scenario that could possibly happen.
I don't think the authorities really resort to such extreme measures just because someone's teaching the concept of Bitcoin, unless they could link fraudulent or large scale activities such as a mining farm.
Would be amusing to see "Man arrested for teaching friend illegal cryptocurrency without consent; friend tipped off police" on their newspaper headline
