thanks.
so they are indeed competitors, right?
doesn't matter if it's an ethereum token or a entirely new blockchain.
No, 0x is focused on the exchange of assets while Ravencoin is the transfer of assets.
0x runs in Ethereum Blockchain, have you ever heard Etherdelta before? Etherdelta is a decentralized exchange, 0x improves the exchange of assets(executing buy or sell/exchanging the assets).
On the other hand, Ravencoin enables the transfer of assets. What I mean here is transferring the assets from one wallet to another wallet.
The real competitor of Ravencoin is ETH, not 0x.
