Bitcoin will be adopted in society gradually, when these young people see that their assets have no value and that the state can take them at any time, that's when they will adopt bitcoin.
We dont just expect everyone to know about bitcoin once, it will happen gradually, the world is so big and we dont expect everyone to adopt bitcoin once, lets talk about our rural areas that dont really have access to internet connections, must of them dont know anything about bitcoin but I know with time they will begin to start hearing about bitcoin. Few years ago just few people knows about bitcoin but currently the percentage of people that knows about bitcoin have increased.
