@Ritch: The Cryptsy exchange doesn't need to constantly withdraw and deposit, since the trades can be instant and you have your own addresses on the exchange to use, so use of bots on Cryptsy can be advantageous.
IXC BOT-Trading on Cryptsy could be nice and 2-3% per day should be possible.
But first of all I would like BCS to offer a user-changeable output-adresse, without asking the support.
best regards
