no dividends, there are however assets that are meant to give out dividents on top of BTS.

I like to think of running btsbots.com bot is my divident and helps the exchange

There's also a referral system for earning a bit on side too you can find in FAQ


OBITS is openledger's thing, not directly bitshare's. openledger is a third party effort to build stuff on bitshares, including ICOO, OBITS, companies they help move onto bts, they run one of the UI websites and one of the gateways.

There's a new bitshares improvement protocol to make it easier to give out dividents for tokens.
