It is difficult to imagine that at first there will be many users at the service. Moreover, payment in the crypto currency is not very popular yet. Few will don't agree with me. Project managers need to think seriously about additional advertising of the project.
I think the guys in the project know what they're doing, well, some yes, they like to pay for Yandex and other wallets, but everything has its time
I do not agree, many already work with cryptocurrency and pay for their purchases. Over time, the cryptocurrency will become even more popular.
