I don't usually do airdrops to avoid being scam because some of the airdrops are scam, but anyways airdrops is same as bounty token, i think the correction question here is how can you manage your token that you can obtain in airdrop and in bounties, For me, I think that you should store it if you think that the campaign has potential, Like me, I think Electroneum and Deep Onion have potential in growing so If had those, I would store it for a long time, until the price is larger.
