You have a large community on telegram. Do you have an airdrop going on or ended?
I think you can use bounty programs and airdrops for promotions. Works most times.
Bow coin had an airdrop. It was on telegram using a bot. You had to join the telegram group to earn bow coins. That was a good opportunity to earn cryptocurrencies by doing simple tasks.
That airdrop still on? Or it's already over? Is there any other bounty going on? Let me check at their telegram channel.
