Which trading bot is legit?

I'm interested in utilizing Trading Bots to automate my cryptocurrency trading, but with so many options available, it's difficult to discern which ones are legitimate. Could you please elaborate on what factors I should consider when evaluating the legitimacy of a trading bot? Are there any specific bots that you would recommend, based on their track record, customer reviews, and security measures? Additionally, what are some common scams to avoid when searching for a trading bot?
