Looks like Crypto States Nations will be a reality in 2018. But without proper infrastructure and public education, all may end up in a big mess..
The most important impact will be market awareness by millions of people who before where not aware of the Crypto Space World or didn't care about it. Now they will feel the impact, weather be good or bad.
I forsee cyber crypto wars and thousands of hackers moving into the space to profit from people careless usage of high security systems. We all have seen how every day, some big name get his hands burned loosing millions of coins.
Already, a number of nations who have recently been issued sanctions have begun to explore state-backed cryptocurrencies. As recently as yesterday, a senior member of the Iranian government floated the same idea, following the People's Bank of China and the Russian deputy prime minister announcing similar endeavours.
While still in the earliest stages of that work, there's already a number of concerns he's identified. For instance, even if Venezuela's efforts to avoid sanctions end up failing, he believes other countries are watching, in an effort to learn how to adapt the model to succeed.
