Yes, crypto bots are useful trading tools. They automatically trade for you according to your trading strategy even when you are on your sleep. They are a good way to make profit buying low and selling high.
I don’t normally classify trading bots as good tools to trade seriously because, to me, when someone claims to be doing something, that person should definitely be confident in doing so by himself or herself, not using an AI bot. However, these trading bots you are seeing are nothing but making a trader lazy or lazy to learn more. Trading bots don't guarantee profit, and they don't always go straightforward, like when you use your brain to trade. However, if you are at sleep, I cannot advise you to setup your bot to trade. That is carelessness, mate. You leaving your money there and going to sleep is not good in my opinion, and did you know that trading bots don’t work all the time as you want? You need to include your skills, so don’t rely on trading bots.
