Earlier quoted context omitted.
A private transaction of BTC wouldn't effect the market value of BTC. It is correct to say 1M BTC = 565M USD; the market price of BTC/USD is only effected when the BTC is sold on an exchange.
Almost no single entity has that much BTC (as of 2016 only ~15 million Bitcoins exist), to acquire it someone would have to aggregate the Bitcoins from many other entities by via buys on a Bitcoin exchange. This would cause a massive spike in the price of Bitcoin. Interesting to note: there has been no new Bitcoin block for the last 1 hour 23 minutes. This happens from time to time, but it is a little suspicious. See…
They don't except it all from a single entity.
