That’s first talk about several characterizes of blockchain.

(1) The credibility

Blockchain is only a reliable storage. All the trust problems we encounter in our society are all the forgeries from the source, such as shops forge credit. However, if the business environment is stable and predictable, why do we need the decentralization of blockchain?

(2) Security

Blockchain is also an address, a password, and there is not much difference from an account, if the frauds get the password, they can still embezzle it.

(3) Scarcity
One of the reasons we use cryptocurrency is that we can avoid the inflation, but both Bitcoin and Ether have succeeded in making hard forks several times. In addition, coins’ value is uncertain.

Besides, most of the cryptocurrency exchanges platform are centralized, they seems work well. Do we really need the decentralization of the blockchain?

BTW, there is an ICO I heard pretty interesting, a hybrid decentralized exchange https://joyso.io/. Is it worth to invest in?
