I had a big problem with his interview. It does not mention bitcoin's reliance on "demand". If you look at bitcoin as a closed system and realize that money that goes in also goes out. The cash from your bank account is transferred to early adopters and used to pay for the huge electricity bills. It does not get stored. It is not there. You cannot get it out. Unless you find a greater fool to buy some bitcoin at higher price. You cannot find greater fools forever, so bitcoin as a system is unsustainable. When people stop believing there will be someone to relieve them the price will go up they stop buying. When that happens and money stops coming, the doors are shut and you are stuck with worthless bitcoin.
