I was thinking about making a ticker plant that processes order book and trade feeds from bigger exchanges. I've been doing quite a bit of HFT in traditional markets, now I want to test some ideas in cryptocurrencies world. Since this project will require investing in IT infrastructure, I was thinking maybe I should make scalable solution and sell it as a subscription to offset maintenance costs? Do you think may be a market for such service (ie high frequency data/feeds from cryptocurrency exchanges) given that cryptocurrencies are too small for institutional investors/traders?
