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.
Do not waste your time, airdrops will promise you to give you coins and at the end they are not going to give you anything, not only that you will have to do some many airdrops that you will probably forget about why did you choose that airdrop in the first place and how many coins you were supposed to get, so if you want to get some tokens join a bounty campaign because at least in those campaigns you will get your payment unlike what happens with airdrops.
