Although, there is a speculative factor in cryptocurrencies, I believe that Blockchain technology will revolutionize many things, even more than cryptoactive ones. Just as industrial capitalism evolved into a liberal capitalism and then in 1929 the crack occurred, and the State had to intervene with Roosevelt's New Deal to save capitalism, and after 1945 a regulatory capitalism was established. Something similar with cryptocurrencies will occur.

Today we live, I think, in a kind of libertarian electronic capitalism, and then when the the mismatch comes, it will be stablished a regulatory electronic capitalism, where governments will have a light participation but participation at last, in the world of electronic money.
