To those who keeps repeating "person X is not investing in bitcoin directly"... what makes you so sure?
I am somewhat sure, because looking at the exchange data for the last few weeks, I am yet to witness any bulk buying deals. He may have bought a few hundred coins, but he is not buying any five-figure or six-figure number of coins.
Somewhat sure? Now you're starting to second-guess yourself.
Looking at exchange data for bulk-buying deals is akin looking at the sky for fish... which is what you're doing.
Why would any person with half-a-brain put that kind of money through an exchange post-EmptyGox when they can broker the deal directly with discretion? Why?
The reason you don't witness bulk buying deals is because they don't want you to know it... Why would places like BitPay or even miners, disclose their client info? Hint: it would be financial suicide.
Ka-Shing, as rich as he is, doesn't want anyone to know that he has thousands of bitcoins--if he has them. Why? Hack target. There is no good reason for Branson, Miller, and Ka-Shing to divulge how much is in their VC wallet. Most whales don't broadcast how much coins they bought or where they got it from, for security reasons alone.
