When a huge global financial crisis happens it just happens to everyone, there is absolutely no way of running from it.
Stocks will fall, crypto will fall, gold will fall, house value will fall. There will be nothing that will profit you at the time of an economical crisis, you will lose money no matter what you are invested into. There is no running away from this at all. Hence there is absolutely no way of profiting neither.
You can always play the short side. I've been itching for many years to trade the ultrashort S&P 500 ETF and other similar instruments, but I'm patient enough to wait for a real bear market. I've watched too many short traders get slaughtered over the past several years to fade the stock market myself. It's the same as watching Bitcoin bears during bubbles.
I just wonder how long it'll take me to recognize it, and how much that'll cost me. Most people won't see a real crisis coming. That's why I don't expect one now. Everyone is ready for blood.
