This is an interesting topic as I was looking into trading signals or arbitrage strategies in Bitcoin. I may have posted this a while ago but there is a research team that predicted Bitcoin will trade below $200. They will begin sending trade alerts on 24 Feb, I wonder if they have any Arbitrage strategies as well. Let me know what you think guys, they are into all kind of stuff, https://www.ddmarkets.com/selected-trade-alerts-packages/
