Would you rather auto-trade based on an algo strategy bot, or have the bot auto-trade based on a live trader?
No bots now and ever! If you are going to trade successfully, you need to train a lot. Work by yourself. The situation can be compared with the person, who wants to get muscles, but he is too lazy to go to the gym. Instead, he gets a small ABS muscle toner and waits for the result. No result here.
You might have a point but the way you compared the two aspects are really different. Building muscles require you to workout and it is similar to working on a gym and working at home that might be a better comparison.
I don't think bots are as bad as people sometimes make them look because all they are doing is automate your trades with the data you enter and the limits you set like stop-loss and other parameters. If you are actually doing large number of trades then bots are a good option indeed because human errors are eliminated and you don't have a chance of making any mistake.
