I don't really think crypto needs to be encouraged, or taught, in the evangelic sense.

Me either. This is more about the introduction to people (and even the interested) and how long one is willing to invest before giving up and moving onto the next.

Conversely, when you approach others and talk about crypto or blockchain and they dont already know it, they almost exclusively reject it. Its too radical.

Yep.

They are too confused by the lies that exist around fiat being "safe" and the govt. backing it up with gold (which hasnt been the case for decades).

I have a friend who has been buying US dollars for 'security'

And yes, everyone will come, so yes "they" will come too, but not because of an argument being won, or a fact being learned.

It is a shame of sorts but, some will always be before others.

The masses will come because they have no other choice, and as an aside because "the powers that be" tell them its "safe", which isnt the narrative yet, but will be.

Once the platforms at support authorities are established, the backflip will start.
