Trading bots have always sounded like a good idea especially for people that don't know much about trading or want decent profit. Even though it sounds like a good idea, I rarely see people use it much or hype it up especially the good traders.
The "idea" of a trading bot is awesome, I understand why people would fall for them and want to spend money on them. After all, you just buy a bot, and tell it to make you profit, you sleep all day and watch Netflix and eat good food and come back home and you are richer. But unfortunately that idea is a lie, most bots can't make you money at all, and the very few that works well, do not make money at all times, only make money during bull periods.
This is why you should stay away from them as much as possible and not buy them. I can see a few that has potential, but none of them worths their money at all and you should learn to trade yourself. It doesn't matter if we are talking about a bot, or a mentor or a copy trading, whatever you want, always prefer yourself.
