This a joke taken too far it can never happen cryptocurrencies has come to stay and it is on a good note that countries like Venezuela, Zimbabwe and recently Iran who had been battling with their battered economies and hyper-inflation had to resort to cryptos to bring a kind of succor to their citizens
All these are indication that more adoptions of cryptos by other countries is on it way thus consolidating the usefulness of cryptos of course blockchain had already gained a wider adoptions due to its vast areas of applications
That is the nice way of saying it for sure. The truth is that they don't really care much about their citizens.
Now, the fact that some citizens look for ways to get some and that way have some kind of insurance and escape from the extremely unstable currencies of their countries is another way different thing.
In the case of Venezuela, for example. They even blocked some mining and Bitcoin/Cryptocurrency sites that are not of their "Currency". So you can imagine the situation.
