Every action has a reaction. Was this Bitcoin story a last straw for somebody,
But, there is nothing new when it comes to the SEC's decisions, so there is no actual last straw.
Besides, if people think Musk will be penalized for his tweets about Doge and Bitcoin that will happen after we colonize Mars, Musk was supposed to stop any tweet about Tesla's business practice or plans without consulting with the companies lawyers, his actions about anything else coins, gold, the war in Syria and not going to be analyzed by the SEC. People hype and trash gold all day, nobody is going to be punished for doing that or for posting doge moon pics.
And I'm willing to bet it won't take long for Musk to make fun of those two new charges and mock the SEC once again, he doesn't care about them, he knows that if he doesn't cross the line in a radical way and involve himself in clear market manipulation and profiting from that he will just pay a few fines and that's all.
Nobody will be able to shut him up, the only way is to make people stop listening to him, but if they DO want to listen to him, then how are you going to stop that without taking a dump on a lot of things like freedom of choice?
