Poverty is good for bitcoin!
Yes comrade, too bad it's 2019 and nations don't pay their workers anymore, except for the government employees.
Indeed comrade, we should take the money from the evil rich countries and give it to the poor so they could spend it and become poor once again. For the glory of the working man and the soviets!!
If he bans the transactions, then the users will go underground. But on a serious note, I don't think that he'll do that. Even Maduro realize that it is not Bitcoin that caused economic collapse in his country. And bans are useless, when he don't have a large police force to enforce the measure. From what I have heard, more than half of the police force have gone AWOL, as the salaries are getting delayed.
The expression "even he/she/x" is losing its meaning when you add Maduro to it, his stupidity is just as the universe, infinite.
And secondary, yes, he has the power to impose a ban, he might not have the police but he has the army and he has his bands of mercenaries, and furthermore in the situation the country is nobody gives a damn about human rights so after 1 hour of interrogation thee you'll remember you are Satoshi's brother. And the poorer people are, the cheaper and more efficient snitching becomes.
