I answer the question above: these companies allow you to trade in cryptocurrencies or other digital currencies for other assets. I would say that this is a multifunctional project.
I completely agree with you. See, there are still such useful features as masternody. This is a network of computers that provides a network platform. Anyone can work with this, for this you need 5,000 PWS tokens and little technical knowledge. What do you think of it?
it seems to me that this looks pretty tempting. I know that the masternodes provide network security and also serve the ecosystem by stabilizing the supply of coins.
