You've probably seen it yourself. The occasional pricing difference between the various exchanges (Coinbase, Kraken, Polo, Bittrex, etc.) I was just thinking that someone might be able to make a lot of money by simply keeping an eye on the various differences in pricing and cashing out when a nominal gain has been made.
I took my thinking even further and am curious if anyone has ever written a bot that will do this for you? It would be very interesting if you could hook up all of your accounts at the various exchanges and the bot will send money between, and buy into other currencies with the small gain. This seems arbitrary, but over hundreds of times with various currencies, the amount would certainly add up.
I guess my question to my friends in the Steemit community is, have you ever done this and did you make money? Secondly, can a bot be written to automate the process?
