Anybody knows if it is enough to join their telegram group en follow their twitter to receive the coins of the airdrop?
You must follow their rules. And submit the google register form.
In the same place, all the rules are prescribed. Read everything is not so difficult. And simply subscribing to social networks is not enough, you need to send your request by filling out the form
In principle, for the airdrop is enough. Most campaigns are like this. It is best to read the rules of each campaign for the pit to be very different. While you are paid to do a job, you have to do it with responsibility with all your heart as if it were your project.
