1) Useless as a currency due to volatility.
So this at the moment is kind of true, not many vendors are accepting btc due to the fact the currency can swing upwards/downwards of 10% in a day. But this is completely disregarding the fact that we are at such an early stage. Price discovery is still a real thing and if you look back at any emerging markets this volatility goes on for years! BTC is 9 years old.
2) No intrinsic value
Is having a completely barrier free value transfer system operating completely neutral politically accessibly by anybody with an internet connection not a value? From up in his ivory tower maybe this isn't valuable but for the billions excluded from the financial system this will one day be life changing
Another thing to add. Peter theil who is also a former CEO of PayPal is one of the biggest proponents of crypto so take this article that has been doing the rounds with a grain of salt
He is the former CEO of a competing company, so his opinion will be biased for sure. PayPal is having a hard time already, I heard they made a lot of changes to their policies recently.
