Maybe there will be a crazy sell off, but most likely it will recover. Theres no better place than USA to put your money or have your assets . If its not making you more, its just going to be worth less. A weakening dollar will spark new trading as well. Everything is an agreed price. Stocks, crypto, metals, trade, currencies. All of it. Based on the leveraged dollar system.
The stock market is going to go higher. It may dip, never hurts to sell and rebuy lower of course, but the world is moving forward. GDP of countries is going up, not down. Even a new trend will still push up. The consensus pushes up long term.
I don't think crypto or metals are linked to US debt. I'd consider they're more linked to the Vix as in they're a fear indicator. And the world is very scared right now.
Just my opinion. Good luck
