i think there would be a cryptocurrency for real estate,but it will be something other than bitcoin and something that a governing body would launch.
Cryptocurrency for real estate would be most likely centralized because there is never a case where anyone can buy or own real estate without registering it to the government. Your personal details will always be needed in purchasing real estate so don’t expect that if there were a cryptocurrency for it is that it will be anonymous and could be used through decentralized platforms.
