With this method, you fund your account and sign up for a trading-bot. A trading-bot is a program that uses algorithms to decide when to buy Bitcoins, and then sell Bitcoins at a profit. Even though you are outsourcing the trading to bots, there is no guarantee that you will make a profit. There are hundreds of such bots on various platforms, although we do not recommend that you trust them with your life-savings. However, you may want to try them with money you are willing to lose.
