As for new ideas, I think of a few but the fact doesn't directly allow me to legally adopt them as doing so would be against the law. How about you, do you have any good ideas for future bitcoin adoption?
Adoption increases when the users are themselves aware of the pros and cons of a system. So I say, we make our peers aware of crypto and how it works, how to keep it safe and what are its pros and cons. If someone takes you a tin-foil hat guy, which can happen when trying to give a speech, avoid them.
But still if governments are giving an illegal stance to crypto, then all your work will go in vain. We can assume that it will not happen, because such moves are taken mostly by conservative sects. Rest are keeping it in a "grey" area and evaluating risks vs rewards.
There is very little you can do as a single person so try to gather a community in your city or locality and see how that grows.
