Lately there have been a lot of invitations to join the Airdrop program, they spread through social media and e-mail, until many wonder whether this program is true or scam?
The question is whether this program is part of the marketing strategy so that there is a crowd in sales? or just giving away prizes to get many participants who are interested in joining this program?
Maybe sender wants to get more refs via email marketing, but my advice for you: abandon links were inserted in emails to against malware to protect your wallet safe.
