for the first time, maybe you can try to follow some airdrops. You only have to enter, and if you are accepted, you will get free coins. but maybe it's not as big as a bounty. but you can try it if you don't have the capital and knowledge for the bounty campaign.
I believe that airdrops aren't that big of a thing anymore, they kept dropping in value as well as the market in general, bounties are still better because they give a good amount of rewards for the amount of work required.
