You should lower your expectation level mate, I dont think the OP here is interested in that discussion rather trying to "fish" for other forum related "goodies".

No offense to the OP though, but I and most members here have seen more number of threads like this and we all know how real these "friends" are. In either case if they think that a few people owning big amounts of bitcoin means they control it, you are explaining it wrongly - focus on what decentralization is and how bitcoin is minted and the supply. Show them how charts have been changing and what happens when price rise or dump starts.

If they still dont understand it, dont force it. It is their money and they are free to use it as they wish.
