The financial sector has essentially become digital with the advent of the Internet, Internet banking and plastic cards, but with the advent of blockchain and cryptocurrencies, the world is changing in all sectors of the economy. Therefore, of course, cryptocurrency and blockchain will change our world and make it digital, but it’s not known how long it takes. Maybe a few years, I heard different predictions, but everyone agrees that it is not until 2020 that there will be a strong development of the crypto industry and its integration into various spheres of human activity.
