Rebates to attract liquidity, about time this came to bitcoin trading.. So assuming your adding all the time your fees are at +0.05%. Compared to stocks it seems in the US you're stuck about net flat for fees after the ECN rebate and it doesn't get much better than that - unless you're doing alot of volume.<p>I don't think people realize when you get better than flat on fees, its somewhat like going from -1% house edge to no house edge in a casino (if you're a market maker type at least..) Gotta have a decent strategy too of course :).. I would imagine in btc quick sharp trends though and in that case you're better off taking - mktmaking can be dangerous.
