I also hope for big volume on the exchange. Until now i didnt have a view. IF the fiat gateway works fluent with anykind of amount than, waves would explode. Imagine this....
Waves will explode even without a fiat gateway, simply because it's decentralized. That aspect is going to be extremely important in the future if the SEC tries too meddle too much with crypto. But yes, fiat gateways would further amplify this effect.
I don't see why Waves should not overtake Ethereum once smart contracts get implemented.
