I highly recommended to have one telegram account for bounty purposes. It is the easier way to have updates from certain groups of bounty hunters who shared airdrops and open bounty campaigns. It is also one way of helping each other by giving small amounts for gas for ethereum transfer or the likes. Then the groups can also give referrals to each other, helping out boosting points. A group should be just below ten members if you want to have a peaceful place to chill than more with so much spamming. Telegram doesn’t need identification, so anonymity still on.
