It is available in a free trial, up to 2 bots, and up to $3000 transaction limit in a month. Your profit depends on your strategy, much the same when you trade yourself in trade exchanges. The advantage is you automate the process, you do not have to deal with your emotions. Every time the bot recognizes a condition that meets your criteria or settings, it will transact the trade.
If you want you can copy my trade settings. I trade using Bittrex . My bot settings are: DCA bot, Sell strategy, trading pair BTC-Hive, 0.75% Take Profit, Bollinger Signal on, 50% Percentage of Deposit with 1 extra order, step of extra order is 1%.

No guarantee but my previous months' performance is on an average of 10 to 20% per month net profit.
