your bot trades in pairs. what your bot bought, gets sold, once the parameters are met. say, if your bot bought 1 A for 1 BTC, 1 A will get sold once the strategy is done, and you will get 1.xx BTC back (minus the fees). then the cycle starts again, once the buy parameters are met. this is actually the magic of the bot. it can do this ad nauseam, agian and again, when you sit on the toilet, while you sleep, while you watch a movie, while you game ... and your money multiplies with a bit of luck and with a with bit of good pair selection.
