I have read an article about some trading bot. These bots will do the trade for you. You have to do nothing but just set the bot according to the programme. These bots are making some good money for their users. According to the content.
I am wondering, is this really possible? Should I buy a bot for trading?
Yeah sure, if you know any programming language then you use any exchange API and build your own trading bots and program it to do what you want. The API offers many services you will normally get on the exchange.
