Does anyone in this community arbitrage for a living?
With all the volatility and many Exchanges to choose from, there should be a wide variety of software applications available for doing crypto-arbitrage, right?
 
Quatloo Trader looks nice, but afaik @fyrstikken only released it on windoze. (i'm a linux guy now)
 
Can someone here name the top 3 crypto-arbitrage apps for me? Google reveals bupkis.
Please and thanx
