Source? I don't know about the foreign banks, ... that's entirely possible. But for permitting cryptocurrency / bitcoin exchanges, even for P2P trading, and/or for allowing cryptocurrency for use in commerce? They certainly know that would make the "parallel market" rate diverge even further, ... pressuring further the birr.

I'ld love to see it happen, but the current Ethiopian regime has made no indication that I've seen that they would be going in that direction.

About the only thing I could imagine is them using bitcoin to get around sanctions against Eritrea, or maybe for transferring funds to Russia even. That would't surprise me at all but they certainly wouldn't publicize that they are doing it.

But I'ld love to be proven wrong on either of my assertions here.
