Bitcoin and cryptocurrencies are more liquid than gold. Them encouraging people to buy it creates more liquidity which in turns benefits all of us hodlers.
Obviously, both of them have some narrative behind why they are pushing bitcoin to whales and average joes. But I don't know if my memory serves me right, Mike Novogratz is a perma bear right?
Gold is generally still prefered as it has stood the test of time, while cryptos are still nascent.
Both has its pros/cons, most millennials still prefer bitcoin and then those traditional investors would love to get their hands on bitcoin.
But nevertheless, this is bitcoin publicity, still good for us.
