I am actually surprised that there is over 27000 people in the Telegram channel of AIDOC. Was there a Telegram airdrop available in the past ?
I don't think so... But they did have a normal airdrop tho that's where most of the telegram people came from as joining their telegram channel was a criteria.
It's a good way of growing the community cheaply, getting the word AIDOC around just ensures more publicity and the name is heard more resulting in more community members and investors
Airdrops is indeed the cheapest way to get attention. They now will not have to worry about filling up their Telegram channel. With such amount of users there will be everyday activity in their Telegram group.
