I have not yet heard that any bank accepts bitcoins, well, or perhaps I missed this news, but I know for sure that many banks use blockchain technologies, but for the world bank to accept bitcoins, of course, we can still dream about this, but so of course, on the one hand, then more people would trust bitcoin, but on the other hand, I do not think that it would be good, because then it would be possible to track people who will make deposits in bitcoin through the world bank.
