Now that I disagree with and have no idea where that figure came from. I would be surprised if the blockchain becomes just as valuable as the internet, let alone 10x worth. Isn't the killer app for blockchain cryptocurrencies? As far as my understanding goes, blockchains without cryptocurrency are just slow inefficient databases. In order for a blockchain to be maintained, there needs to be a valuable token to incentivize the maintaining of the ledger and upholding network security.
