The money will always persist because it is controllable and the authorities want the full control over the society. They can achieve that kind of the control with the regulations of the centralized currencies that everyone are using. Centralized currencies are deeply connected with powerful people that are on powerfull positions and there is no way that the money as such will cease to exist because of the decentralized currency that is existing for the last couple of years.
Bitcoin, although it has very good perspective, needs to be improved in many ways for the people to be aware of its usage. Not many people are believing in the Bitcoin because of the fluctuations that are causing the instability of this famous crypto coin. I hope that the future will bring the merging of centralized and decentralized money and that some kind of balance will be brought by the new system of the payment in the future.
