I think the problem here is that there are still very few altcoin specific merchants who want to accept payments. For Bitcoin you have many types of payment processors like bitpay, so people don't have to worry about settlement. The only hope is to ask BTC accepting merchants and processors to also accept ETH.
Checked the list and there's nothing I would like to buy there or that I could buy cheaply being in Asia. Good list though.
I've actually never bought anything with Ethereum (I only hold it) and that just says a lot about it, doesn't it?
Take a look into this website or map:
https://coinmap.org/view/#/world/22.51255695/13.71093750/3You would able to see merchants around the globe that do accept various alts into their establishment and also this one includes atm machines nearby.
Its good to see for a global adoption not only focusing in Btc alone but also on other alts as well but as anticipated this will always target out on
top ranking alts.
