I'm not a bitcoin booster or super believer or whatever the term is (even though I have some), but even if we are to follow your arguments, and assume that Chinese traders got the price that high, we can say that with a market cap as low as $10B, China hadn't likely injected as much money as Wall Street would if they entered the market. My point is that even if the price crashes because of some bad news in China, it still has a chance to rise again when Wall Street comes (if we are to believe that those companies still want to enter).
It really looks like speculation is what keeps the btc/usd pair rising, but with such good news coming, I can't think of a lot of reasons why people would stop speculating. Keep in mind that there is no short supply of people who want to get rich with little work.
People were saying this in 2010 when it reached dollar parity, in 2011 when it was $20 a pop and they keep saying it now. It really means nothing.
Also, you're getting downvoted because you're making these hard and fast predictions without substantiating them with anything but pure speculation. If you really believe BTC is about to drop then why don't you put your money where your mouth is and short it? There's a fortune to be made if your predictions turn out to be correct.
At this point I am not comfortable investing more in BTC but I would also be very reluctant to bet against it. I currently believe that the chance that BTC will reach the levels the Winklevii are talking about is minuscule, otherwise I would've already dumped all my savings into it.
I have a dislike for people who keep preaching either about BTC completely failing or overtaking the entire world economy. Both belong to the same camp of irrational thinking and simply hoping their preferred outcome happens. There is a certain probability distribution associated with the future price and the chance that the price will be at the either end of the curve (0 or max) is tiny. This is why I always tell people who make black and white "predictions" about price to simply invest according to their beliefs and certainty levels. It usually reveals real quick what they really believe (more often than not, they're full of shit).
