Arbitrage is less profitable now that a lot of bots exist.   As I said I have abandoned this for a rolling buy sell bot which is proving more profitable.  I did make several B over the course of a few weeks using this bot.  I would think that other exchanges and auto transfers could be added in order to take advantage of the dozen or so alts out there with different prices and faster transaction times than B.

All of that said.  I'm not one to turn down making even $.01 a day while I sleep, eat and work.  Free money is free money.
