Looking at those campaigns now available its really attempting to join those projects were bounties are given per stakes. Honestly we can really gain more profit out of it instead of airdrops. Yet we should really pick those projects who already have a working blockchain or atleast already have a product to be presented as they do ico. Reading on some sentiments of bounty hunters now, there are lots of ico projects exists that are not paying. So not unlike before that most of coins alloted for bounty are escrowed, we are atleast 90% sure we can receive at the end. But with this bearish market nothing more wiser but to hold and accumulate either thru bounty or AD. So depending also on airdrops. My experience right now as I choose to gain thru it, I'm receiving a good amount of Privcy and Staker token which are both listed on exchange and community driven cryptocurrencies.
