Definitely not. And despite the other calls, angel investing is a terrible idea as well, imo $450,000 may seem like a lot of money, but in the grand scheme, if it's your entire life savings, it's not. Investing in one company on a secondary market or investing in a handful of startup companies is pretty much as high risk as you are going to get. If you were a normal 9-5 worker, the traditional advice would be to invest for retirement using normal means. Index funds, stock market, bonds etc. I don't think that's a bad idea here. Instead of going for big returns, which also comes with the more likely result of big losses. I'd suggest you invest in yourself. Use the money to be able to have a bit of a runway for your own projects. There will be expenses, but fortunately you have some funding for yourself. Hopefully you won't have to use most of that money before you start turning a profit on your projects. Then continue to save money for long term retirement, or maybe you'll want to buy a house eventually.
