As I mentioned in some previous posts, any other BTC / Crypto adoption from here on is out of our hands. What we mustn't do is preach the BTC gospel to everyone and anyone, that's bad and it's ineffective, even counterproductive.
I wouldn't say it is out of our hands. It is out of our hands individually, but as a community it is still in our hands. Meaning, if we want to help people adopt to bitcoin a lot more, we could literally move that direction with our money. How? For any project that is aiming at increasing the adoption, we could help them with our money, it could be using them, it could be investing into them, it could be supporting them with chatter, it could be paying them to keep going (patron style) and so forth.
Basically, we could still voice our opinion on the matter as a whole. Sure that is not just one person going around yelling bitcoin to anyone, but as a whole we can still do some things.
