It's not certain where Petroleos got the bitcoin and ethereum, let alone how much it has. There's also no guarantee that companies would accept such a move when crypto's relative anonymity and the potential for money laundering leads many other banks to hold off.

This is a Hail Mary effort to sustain Venezuela's economy (and thus the Maduro government), and it may ultimately amount to a risky experiment even if it goes ahead.
