So I browse Tildes, Hacker News, and Reddit, but I'm wondering if there are online communities or hubs out there where entrepreneurial folks discuss actionable business problems and projects, instead of news or memes.

I notice that people will spend endless time online discussing the minutiae of their personal lives, celebrity lives, politics, and son, which are fine. But I want to read about how people are working out the kinks of drone delivery, improving access to and availability of mental healthcare, making municipal permitting more streamlined, and other processes.

Lately I've been thinking about withdrawing most if not all my money off the bank and investing in a safe box, but I'm not sure how wise of a decision that is. How does everyone here go about that? Do you keep your money in the bank? Do you have a safe box at home? Why one over the other? Do you invest some of it, say in things like cryptocurrencies/stocks? What would you recommend or advice someone to do in regards to this if you could?
