The problem with bots is the marketing and not the bots themselves. People act like buying a bot would mean that you will profit better than you could personally and that is NOT what trading bots are all about, they do not provide to trading anything more than what you provide because if you do not know how to trade that means you can't make the bot trade better than you neither.
Yeah you are right. For marketing purposes they are advertising with catchy words like big profits through bot trading but practically only up to the level of profits what manual trading is making alone possible with bots and if we run bots all 24 hours then we can make significant profits with respect to more trading hours.
