To me, this seems as inevitable as India banning cryptos. These rich guys enjoy the control they have over the monetary system, but they are starting to realize the gig is almost up. If they really want to stay super wealthy, buying into crypto is a good idea. Soros drops a billion into Bitcoin today, in ten years it's worth fifty.
Killing Bitcoin wouldn't do much, people would just start using LTC, or DSH, or any number of existing currencies, or a yet to be invented one. Getting in early is a way better idea.
