At first I tended to be very optimistic about the future of cryptocurrencies in the long term, however we must be aware of the following: ten years ago, nobody ever imagined that something as advanced and sophisticated as bitcoin would come to emerge virtually from nothing, to become the technological revolution that it is today. In the same way, at this moment I think that no one can visualize what technology will be offering us to solve the problems that right now the blockchain can not solve, so I am convinced that in 2028 the technology will continue to surprise us with more advanced solutions than we have now.
