For example if I would like to delegate POB or LEO to @ctpsb, I would be paid a yield in $CTP sent to my account right?

At the moment we can only pay dividends on Hive delegations. People can delegate their hive-engine tokens and we will use them to upvote the posts of the community and like that they profit as well from their delegated tokens.

This project is multi-curating therefore? Having a single account to curate multiple communities? (as @hodlcommunity with Leofinance + Hive for example?).

We are trying to curate in as many tokens as possible but it's getting more and more difficult because with the new smart contracts it gets difficult to work with vote weight multipliers. We do as good as we can :-). At the moment we curate in CTP, LEO, SPORTS and also ONEUP.
