How can these people know how much money the Winklevoss twins have, besides their investments in Bitcoin.
They might know the bitcoin wallet address of the twins and as far as I know it has been exposed that they are known for having 120,000BTC.Winklevoss twins are already billionaires and they will just keep those bitcoins for years just like a gold reserve so "ex-billionaires" stands for nothing.
You know that you can have several different wallets right? You do not have to use the same wallet for everything. Even if
someone figured out what their Bitcoin wallets were, then they could still use that for show.. I would use Bitmixers to hide
my wallets linked to my main wallets. They also own an exchange {Gemini} where they can hide dummy accounts, but I
doubt that they would be doing that, with all the KYC/AML regulations.
