The process of talking someone into bitcoin should be smooth and depend on the personality of the person rather than trying to force them into bitcoin, if they have no interest or even against the ideas of bitcoin, You shouldn't try to push them IMO and just use the seeds planted that may later shift them into bitcoin rather than fruitless discussion.

I gamble and trade USD to BTC and vice-versa, gambling and trading can be very close sometimes if you trade randomly and will have no difference to gambling in general, but using indicators and trying to predict using news and the like can make it a little different.

That's not the fault of bitcoin, but the financial inefficiency of most of the countries banning it, or the fear of an unregulated currency in some countries -which do not believe in anything "free"-
Russia and for a brief time China, banned bitcoin for users due to the fear of increased devaluation of the currency if was traded directly to USD, something these countries are used to doing monopolizing the economy of their countries. Ecuador, mostly due to fear of the unregulated community and currency.
