Using a blockchain as storage is the most reliable method to make sure data is always available, not corruptible and cryptographically secured. This is ideal for when you have ownership of data and you want to be sure it can not be altered or copied and you want the right to grant and revoke access to it.
Data monetisation is made easy with blockchain technology. No more middle-men taking a cut; your data is worth money and now you can earn directly off of it! With micropayments, the ones generating value can now actually store and transact with it.
