Lets make a very conservative assumption, that only 10% of IT and financial services will be improved with the help of blockchain technology and will depend on blockchain in the future. That gives us $3.1 trillion in utility value, which blockchain technology can provide. Once again, this is a very conservative estimate.

Hilarious...
You know, since this whole world runs on electricity is somewhat of a mystery that electric companies are not worth also 31.31 trillions.
Or how Toyota and Volkswagen Group are bigger than RDS since their cars run on gas.
A company can implement a blockchain solution with no coins, no value just like a database.
Not all blockchain solutions will have coins that will be traded on yobit.
The whole point of blockchain technology it is its decentralization.
If a company implements its own private blockchain, it won't differ from usual database with many backups on different servers.
