Airdrop is a good way to get free tokens, but it always takes much time and brings few rewards.
When you join in an airdrop, which step do you think waste your time? For me, the answer is "Submit Your Details".
By the way, are you still willing to join in airdrops? If not, why?
Today, I see no reason to participate in social bounty campaigns, it does not bring any profit, every time I participate in a signature campaign, I dont consider it to be earnings, it's a job in my spare time.
