is it a token or a coin ? will there be mining or any other way to generate passive income ? I don't really understand how this is going to work in practice.

Nowadays many projects prefer to use PoS for consensus. That way they are quicker and do not require so much electricity. Also from a consensus security point of view its better for the network to be backed by a bigger stake, that makes sure the token holders are diligent and don't let the price of token fall by voting for the strongest miners."

I wonder if advisors invest in your project or just get tokens for consulting your project?

It would be really hard, but they have a chanceto do it starting in the Philippines.

All cryptocurrencies (stable or not) are being used for cross-border payments around the world for a long time already. What new has ROKS made?

Rockstable project has already chosen it's strategy and road map and there is no need to change it.

48 exchnages is huge number for such a country as the Philippines. How about conquering most of them?
