I like it

You know what would be even better? Let's say that an audible warning can be set for a certain price - how feasible do you think it is? Fireworks for the new ATH of course

I added both your recommendations.
Now users can set an alert if the price goes above or below a set price.
Also, When the bitcoin price hits a new all time high, the site will display fireworks in the background.

Enjoy and feel free to share any feedback to make it a better price tracker.
