There are several experts in the world who claim that Facebook and Google are preparing to launch their own crypto-currencies. It is hard to imagine that analysts of such advanced campaigns do not understand the potential of a growing market. There is an opinion that these campaigns are preparing to launch not just their own crypto currency, but a whole range of services, built on blockchain technology. I think the launch of services by such giants will immediately raise the capitalization of these currencies. To what extent, it remains only to guess.
