Has anybody tried this yet? (Not sure if alpha rounds 1 & 2 were public)
I've been making pretty decent BTC returns with automated arbitrage trading (see link in my signature) but I'm really excited about Elqnt because altcoins are involved. (Let's be real, BTC will not hold its place at the top of the market cap forever).
