Everytime when I am choosing a bounty campaign I do a deep research about the project, team, future perspective and also do a calculation of possible rewards. Then I will choose the best one. 
Old bounties were more profitable than new bounties, if we compare advantages between new bounties and old bounties. Yes indeed, new bounties give you token, you don't have any opinion about the price of the token. But in old bounties it was the average height above 100$. l would prefer old bounties.
