Are you sure this is true? If you bought bitcoin in 2009 when it wasn't of great value and kept it until now, that is correct. But if you start investing now, I'm not sure, and to become a dollar millionaire, you need to invest a huge amount of money. And if you only invest a few thousand or tens of thousands of dollars in bitcoin, you cannot become a millionaire even if you hold it long enough.

I don't think the government is looking to stifle bitcoin, but rather they are looking to control it, but they have a lot of trouble, and I don't think they will succeed. They know its potential and also want to use it at their disposal, they are not going to destroy something with such potential.
