I am not great in trading but all I know is that I usually gain profit but not that big as some of the great traders here. I think I will consider Bot to do the trading for me.
This is a wrong approach. If you want to trade then do it on your own rather than using a bot. A bot only automates your order placing and running some algorithms. These bots are the reason Binance Sell walls become so high and make a fake market impact in terms of aggregators like coinmarketcap. Overall they have a bad impact on the crypto economy and neither does using a bot guarantee your profit.
However we have some people who are trying to make money by selling bots. So they will feed any person they can find with their BS propaganda about bots and how they can be used to get profits. They are nothing but lies.
