Obviously, no landlord accepts Bitcoin yet so I had to sell a portion for EUR.
Another obvious use case: If you change the denominator from USD to the FED balance sheet, the S&P just went sideways since 2008. So did everything else.
Bitcoin for me is an inflation hedge and I have all my wealth in the digital space at the moment. Bitcoin, Ethereum and Polkadot. I am simply waiting for StartUps to build more use cases around the space so I can safely stay there until I die.
So: Payment and escaping the destruction of FIAT money by the central banks.
