OF course he would not be totally against it. If anyone understands how fiat currencies, he would. His predecessors came up with the idea, for pulling the world off the gold standard in order to control the wealth of the world via the Federal Reserve Note in their New World Order for greed of power and wealth.
Digress: Now with Coin Base on the market, you know they're still controllers via the globalist banking system and in collusion with the US Government's regulation via the internal revenue service. In the meanwhile Coin Base is still another option, but only use it for investing, buys and trades, but not for something such as online gaming of any sort unless you want to risk your assets with them getting frozen...and keep good records for tax purposes.

Anyhow, the guy knows this is technology to stay, and he knows wealth to be made. I would not be surprised that those globalists had come up with the idea of cryptocurrency, because they know that physical fiat monies are failing, and their own greed has cause great debts worldwide that not even the USA, UK, nor Europe will ever recover from. I would not be surprised if they instigated it to make like it was all Satoshi's idea, or whatever his name is just to get this thing going and to distract the world from them, the man behind the curtain. Even the Bible details about a cashless society, and this is the precursor to it be fore the anti-Christ ever takes over.
