Starting a hedge fund from scratch

Hello everybody. As the title says and as it was asked here before, I have been thinking for some time about opening a hedge fund. With this thought came a lot of questions and fears regarding such a decision, and I wanted to ask some professionals from around here some questions about how to start and operate a hedge fund:

  1. How much capital would it be recommended to have in order to start a hedge fund? Can you start a hedge fund with almost nothing, or do you need at least, let's say, 500k?

  2. How lengthy is the registration process?

  3. Dear fund managers and analysts, how do you find clients when you are at the very beginning? I find it quite hard to find clients when you are starting from scratch without having been previously working for a hedge fund / asset manager.

  4. How stressful is the life of a fund manager?

  5. How do you manage risk? What tools / software are you using for risk management?

  6. How does risk reporting to the clients work? How often are you making risk reports for clients (yearly, quarterly, monthly)? Did it happen that your clients asked for risk reports out of the blue?

  7. Beyond strategies and elaborate thesis, what quantitative skills would be necessary? Is knowing Python(with Pandas and Numpy), R Studio, MATLAB, Java and C++ enough?

  8. How complex is data management? For sure, it is complicated, taking into consideration cyber security concerns and large datasets, but I would love to read your opinions.

  9. What are the most difficult aspects of clients and investors' management?

  10. How are you dealing with complience and regulations?

  11. For those bad days when you are losing money, how do you deal with it, and how do you get yourselves back on track?

  12. How do I get the necessary equipment for trading? (Or from where can I buy). Like, those Bloomberg stations and keyboards, do you receive them upon buying a Bloomberg terminal subscription? Or is Bloomberg leasing them?

  13. What's your opinion on activist investing? Is it worth it?

  14. How do you find a good auditor? Do you trust Big 4 firms?

For anyone who read until this point, thank you for your patience. I appreciate any kind of advice, and I'd love to hear your stories and learn from your experiences.
