What implications can this step have on Venezuelan economy being the economy with highest inflation rate and simultaneously what does this mean to cryptocurrency world wide?
It will just give them more source of tax, and might help improve their economy(a little) but so long as Maduro is the president, that country wouldn't see a massive recovery on their economic status. To the cryptocurrency as a whole, I think this is a good way of exposing it to the public since Venezuelan citizens might want to use crypto to hedge funds temporarily against their own national fiat currency.
