Fiat price doesn't correlate to the strength of the Bitcoin Network. It's definitely stronger now than it was at last ATH.
That being said a higher fiat price is good. Most of us heard about Bitcoin because it had a huge rip in price. That's how I got into It I'm 2017 and that's how a lot of people got into it in 2021. If we start going back to ATH it will get a ton of press coverage and lots of new people will learn about why Bitcoin exists.
