How were messages and letters transmitted between people 50 years ago by mail, shipping and distribution until the fax came and then the phone and even social communication with voice and image and like that life and its methods develop with the development of technology. This is what will happen in a few years in buying and selling and trade and everything related to financial matters. Everything will become digital and the traditional method and tangible currencies and carrying them will become a thing of the past in a few years. Whoever invests in this field will follow the development train and will reap the profit and whoever lags behind will inevitably regret it. Therefore, everyone learns and everyone practices and buys and trades and will gain and achieve what he wants. In this era, success has become between two options: either keeping up with technology and winning or lagging behind and failing.
