I think it is because for most currencies you need to buy bitcoin to buy the currency you want. But luckily there is the Gulden (NLG), what is getting more accepted day by day in The Netherlands, if i remember it right they are gonna have a direct eur/NLG exchange from next month. So I focus my hope on this project, oh and they are improving segwit now with there PoW2 update so transactions will be even more fast than it is already.
