the russian propaganda machine is stronk with this one
if you dont believe me theres a good netflix documentary about what they do keep your money heres a bit from USNEWS Maduro's government has a poor track record in monetary policy.

Currency controls and excessive money printing have led to a 57 percent depreciation of the bolivar against the dollar in the last month alone on the widely used black market. That has dragged down the monthly minimum wage to a mere $4.30.

For the millions of Venezuelans plunged into poverty and struggling to eat three meals a day, Maduro's announcement is unlikely to bring any immediate relief.

also DHS (Department of homeland security) has announced its illegal to own any PETRO coins and any venezuelans found holding such coins will be denied US entry/ US visas this may soon apply to the European Union
as well for money laundering and drug trafficking.
