I'm not sure that Binance will offer the UDS/EUR pair for all the currencies they have, actually right know they don't even do it with USDT, so I don't see why they should do it with the real fiat. For sure it can make easier getting some coins without having to get through BTC or ETH.
I also think its good to get altcoin or token without converting to bitcoin or etherium first.
Binance try to give extra easy for their user and want to make binance more known among people in all over the world
I also think this is a good news for both btc and other altcoins, in the past months, several exchange regulations have made the market fell several times. With the support of the Malta government, it will sure to recover.
