I think that's a great move on binance's part.  No idea whether it will increase adoption, but it'll make it much easier for people from different countries to buy crypto with fiat.  Right now I don't think there's any exchange in existence that offers trading with that many currencies.

The big issue with this I think is going to be kyc procedures, which I'm certain will follow when someone plans to use fiat.  Kyc isn't exactly popular, but it may not be as big a stumbling block as I'm thinking it might be.  In any case, I'm all for this but I'm wondering what sort of regulatory BS binance had to go thru in order to get this approved.  180 currencies means a lot of different countries, right?  Even just to accept USD on an exchange, they have to go thru the FCC or some other gov't agency to get it approved.
