ZETA platform and the whole SPINDLE ecosystem is powered by SPD tokens. Thus, all the transaction and operations on the platform would be done with SPD. If you meant swap - yes, ZETA will have it (for ETH, BCH, Litecoin and etc.)

I would not say that the rating is small

how to protect yourself from scammers for example there is a list of nicknames moderators anywhere?

yes, sure. You can click on Telegram chat to see who're the official admins

will there be any additional security features for your application? such as binding to a phone number or mail for more protection?

will there be any way to reflect the blocking of Roskomnadzor about the telegram on the servers of your project?

Of course. If there will be need to expand the team - we'll do that
