That's definitely not fresh idea, many such automated systems are already exsiting, but still I think they are not good enough and that's why new projects are appearing. Arbitao has some unique features and it can become the main arbitrage platform
Well the feature surprised me is that users can just contribute computing power to the platform itself... but actually it sounds kinda fishy, just wonder how it is supposed to work
I don't get it fully too but the more computing power they have the more efficient the platform becomes. I mean there will probably be more possibilities for trading and you can earn more if the system is stronger)
