Hi, I don't understand whether Bitcoin trading platforms like Haasbot and Butter Bot use pure arbitrage.  Pure arbitrage, in case you don't know what it is, is used in sports arbitrage betting, and a definition of it can be found through a Google search.  These platforms use future predictions to determine the best bet, like in Forex trading, and I don't understand the point of that.  So... do they employ pure arbitrage or not?  Thanks in advance to anyone who can provide an answer.
