I believe everyone had some dreams to achieve when moving into cryptocurrency. Which part of it has not been met yet?.will they be met anyway?
Usage in real life. How many of us wanted to go shop and buy things online with our bitcoin? But currently, its not happening because of to much factors. Although there are merchants that readily accepts bitcoin, they are just minority. We are all talking about mainstream adoption, but to consider it mainstream, it should be universally accepted as payment system first. The thing is, its not on our control, and all we can do is hope that at least some big retailers would experiment and see how bitcoin and crypto in general can be used online.
