"You can take a horse to the river but you can't force it to drink"

Meaning you can render or offer help or the best solution to someone but you cannot force them to do as you said.

I prefer people to make their choice, sometimes when i am being asked personal questions by friends, i rather give an opinion on the subject instead of giving them direct order, particular when it involves financial transactions. Talk about Bitcoin but don't try convincing anyone to it.
