Sorry to urinate on the parade, but this is not a "real" ATH. The last ATH was an ATH in all currencies, this is only an ATH in USD.
So it's not bitcoin that has gone up in price, it's the US dollar that has gone down in price.

don't get me wrong bitcoin, is going up in price, and I'm glad it does, but it's not going up as much as it seems from a US dollar viewpoint.
