I read about the master nodes, it's quite difficult and not every bang will be able to set it all up correctly, in which case will it be beneficial for the end user?
Yes, of course you are right, but as far as I understand they promise to provide a convenient service, where all the settings of these elements will be automated and understandable by the user.
On the one hand, this is good, it will help attract a lot of new users, but on the other hand, users who do not understand such technologies can harm the platform.
