Velox strategies are completely unique which cannot be compared as it once already proved achieving all the plans they incorporated throught their white papers and there will be no token of failure with Velox.
They're not though? Decentralised and Anonymous exchanges have been a thing since ages at this point, say take Etherdelta or it's fork, forkdelta
Those are only for ethereum, you can only trade tokens on them. This going to be for all coins, but it's true that Velox is not the first one because there are some other exchange although most of them are crap. We see if this be good or disappointed one as the others.
its going to take a lot of time and resources for this to be executed well - i hav hope though. at the the vry least they have the name and look to carry it
