using a bot is not the only way of making money and it certainly is not an easy or guaranteed way of making profit while trading.
in my opinion if you have no trading experience then buying a bot is throwing your money out the window.
and besides in trading you can always do things manually, take a position and spread your buy orders, then decide on a profit and start putting up some sell orders. if your speculation of the market is good enough you will make money easily like this. and if not no amount of bot will help you.
I suppose this is a bit late for the thread but since someone else wants to know, I disagree. I actually haven't bought a license, but Gunthar gives a very reasonable explanation for it. All the bot does is make very quick decisions based on parameters you set (how much change there should be, what currencies to trade between, etc). It is not trying to be a substitute for real trading l, but it can be effective as an aid to real trading.
