The upcoming smart contracts will be interesting in that regards for guaranteed income streams that don't rely on you getting a number of their tokens to begin with but straight income through the contracts as well. Also interested to see what kind of tokens will be created and how they will work through HAF, i.e. what the costs will be and what kind of fees they will have for trading, etc, preferably the best outcome for Hive would be if they all relied on RC usage for smart contracts, etc.
