First of all, NEO has a specific asian marketplace in the crypto space. Though with a lot many Dev Cons and updates they are trying there best to touch base at ETH level. However, most of the project we see on NEO are still coming from Asia.
Talking about worldwide acceptable currency, please, both NEO and ETH are having no currency use case, they are never going to be accepted as a currency for buying and selling goods. They are meant to be smart contracts to enable dApps and ICO contracts.
thanks for your valuable answer.
because ethereum has been trusted by china country and become number 1 there
because ethereum itself has good potential in the future and its development is quite significant,
so I do not think we need to doubt about ethereum anymore
