The Future Of Money

What is the most important thing in the world that governs everyone's decisions on a daily basis? What is the key factor that runs the markets and controls its reaction? It is money. Money basically runs the world. Without money, everything will be different. Money helps in stabilizing the world, it provides everyone with a unit of value to determine what the price will be for a certain thing. There is no more barter system required, it was slow and inefficient.
Money solved the issue for it. But the question is, with the world developing in the field of technology, what is the future of money? It is very important to determine how the money will behave in an economy where everything will be decentralized. How will people make use of it? Will it pose some problems that people aren't able to understand right now? Only time and research will tell about that.
