The world is heading towards a new economic order. Production vehicles were much more valuable in the past. Now the material power can keep the money constantly. This cycle needs to be broken. Cryptocurrency can break this cycle. This is my opinion. It can do so with a limited amount of money and a transparent transfer system.
We should be careful and differentiate between cryptocurrency and the underlying technology - blockchain. In my humble opinion, imposing Bitcoin as global means of payment is ambitious and complex goal to attain. On the other hand, the blockchain tech, the infrastructure is slowly but surely gaining traction and almost in all sectors business are exploring or developing blockchain based solutions.
