Bitcoin never depends on USD. It is NOT like USDT, USDB, or other stable coins. As far as I know, instead, the Bitcoin value is increasing while the dollar is decreasing its value lately. We can see it during the pandemic, the price of BTC is still able to increase and now it still keeps increasing.
Additionally, Bitcoin's price will not lose its value as long as there are still many people and user trust in BTC, use BTC, hold, and also trade BTC. The crypto market shows how precious and valuable BTC is.
