If US debt continues to grow, people lose confidence on holding or using it as a saving and this is great one for bitcoin because it increases its demand and even adoption
I doubt people will lose confidence in the US dollar simply because the US debt has increased. It has been high for a long time, and nothing happened. It might create a demand for bitcoin, but it won't be significant enough to cause a loss of confidence in the USD. I don't know what caused the recent demand, but if it's the news, then it will just be a short while. With time, the dollar will gain momentum again. Although I didn't notice much change in the price of the dollar.
No need to celebrate fiat losing value anyway. Even though we might have a way to protect our savings with Bitcoin, we would still suffer inflation.
