The trading bot will not work unless there is no programmed with the human. I think the best is the BOT or an AI automatically set the trade for you there is no emotions, doubts and regrets about the decision unlike the human there is so many denials and doubts on their mind if they are gonna let go their position or not. No matter what is the best but the aim is the income if you are winning with the Bot go for it but if you think you can handle doing trade why not on your own but the problem is the time this requires allotment.
Both have a particular role in trading, As long as we're able to setup the bot and know what altcoins or crypto we actually prefer and thinks have a potential for growth. We need to program the bot properly setting stop loss and settings that will make the trade smooth or less risky but we need ourselves to be attentive on monitoring the market to know whether the prices will be affected by the economic news or simply the hype of news.
