Nowadays it is just a waste of time and effort to participate in these bounty campaigns. You need to spend 2-3 months on them and in the end there is a 10% chance that you will receive a small reward (<$25). And even if you manage to receive the tokens, because of the high ETH gas price it will not be viable to move them to the exchanges and convert them to Ethereum. And then there is a 90% chance that you will remain unrewarded despite your hard work.
