What Tesla did with bitcoin could be considered market manipulation, and that's a serious crime considered by the US government. The fact that the company invested $1.5B and make it public that bring a lot of investors to bitcoin, and after that, we see how bitcoin has a crazy jump in the prize, and now they sold the 10% when bitcoin was on its ATH.
As a reference, I will leave this link:

From my point of view, there is another perspective that can possibly be the reason. The commonly known Buy and Sell procedure some people who hold bitcoin in a big amount are people who bought bitcoin that is the same with Tesla and Elon they just did not make it public.
Also, there is also one reason that can possibly make the big cost of bitcoin price going down is there is a lot of countries today year 2021 banned bitcoin that instead of them seeing value bitcoin is shown as a treat to them which definitely made a big impact which is 6 countries when I search the internet/ Google to my surprise its actually a lot from only what I know there is only one country that is Algeria.
Here is a new article about it.
