I think that absolutely can happen with the development of science and technology. Revolution 4.0 has and is happening it happens fast, powerful. Won't be long now, people will grow quickly. At that time, will paper money will no longer be used. The country will gradually change possible to use electronic money, today electronic money has not yet been proved should be very difficult to develop in a sustainable way. It needs to be checked go, the SEC is a typical example. And this market is still too small, need to grow strongly in the coming time. To on par with stock and not too distant future.I predict 5 more years. we will be using electronic money in a broad way at the store to shop, watch movies, payments, or anything that we have.
