Has anyone made a successful trading bot?

I'm curious, has anyone in the cryptocurrency and finance community actually developed a trading bot that has consistently delivered profitable results? I've heard about the potential benefits of automated trading, but I'm wondering if anyone has put it into practice and achieved tangible success. If so, what strategies have they employed? Are there any common pitfalls to avoid when creating a trading bot? And finally, are there any recommended resources or tools that can help aspiring traders get started in this area?
