Given the fact that Aeryus will support most digital currencies - they will definitely not restrict users to their application.
However, its much easier to operate with cryptocurrency using just one application.

Hey Roman. The application allows you to use any digital currency in your wallet. This should be easy and safe. So, we are waiting for the launch of the application.

Yes, but unfortunately so far none of them have been able to achieve stable and fast work of the blockchain ... I hope for the future of crypto, and Bitcoin in particular, however, it must be admitted that even an ancient VISA has more transactions per second than the blockchain...

However ... as more nodes are attached, the network will increasingly verify transactions. As soon as it's large enough, it will become faster and potentially cheaper than VISA.
