I think the question of adoption can be answered form many different perspectives. We might not see crypto become legal tender for real adoption. The real world use can simply arise from use of tokens within the platform or even cross platform. This use can be payment, rewards, stake, etc.

I think we are at more than one level using crypto as medium of exchange even now and as time passes buy we probably will see a rise in this use. We can also see more use case scenarios emerge with time as well
