That guy has no idea what he is talking about, 0x already have a working product you can use their OTC here:
https://0xproject.com/otcto be honest OTC is just a demo, not for real using.
By the way, from Ethfinex whitepaper "We cannot do this alone, and Ethfinex will contribute to and collaborate with other decentralised exchange protocols, e.g. 0xProtocol [1], as appropriate."
Like thousands of other projects this one is no different than others, there is absolutely nothing that you could do with them. if you show me a
Working product that we could use these tokens to purchase them I'll pay you $500 when I say there is no real project it means there is no real
Project, they offer nothing they just say what they'll do in the future. show me one token spendable in some place other than exchanges and I will
Pay you another $500.
bro, when RadarRelay and Ethfinex (both will use 0x protocol) will open and start trading - can I get my $500?)))
