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:

I don't think that can be considered as market manipulation because Tesla didn't tell anybody else to buy bitcoin.
The company had bought bitcoin for itself and sold the 10% of the holding when they wanted to.
If the people are reacting to their trades then it's not Tesla's fault right. We can't blame them for buying bitcoin.
