Great post. I hope that we don't always mix block chain and currencies in the same package. I believe for the blockchain to work it needs removed from cryptocurrencies. The blockchain is richer and much more valuable by itself.
Decentralised
It is important to note that one of the biggest benefits of the blockchain is that it is decentralised.
One has to wonder what would of happened if the American Elections had been done under a block chain?
Here's hoping the current holders of power embrace blockchain. I feel that they won't embrace it with open arms...
