2. Tesla announces that Bitcoin is good now and that it bought some.
3. The price of Bitcoin goes up, because institutional adoption of Bitcoin is good for its price, but also because, by the Elon Markets Hypothesis, anything that Musk buys goes up.
4. Tesla sells some Bitcoin, making a profit.
5. Musk tweets that the price of Bitcoin is too high.
6. Bitcoin prices go down due to the Elon Markets Hypothesis.
7. Go to Step 1.
How is that not illegal?
If we look at it from stocks, if Tesla bought a million shares of random X penny stock, and then Elon Musk tweeted that this random penny stock is now amazing. And then once it reached $10 they sold 10% at 1000% percent profit.
That's illegal, so why is crypto not?
Edit: It's actually legal... so nevermind.
