Doesn't matter , airdrops are free , you will not lose anything ,just join anything you can see and test your luck whether the one you received actually rockets
You loose nothing but your time. Spotting fake airdrop project is indeed simple and complicated. The steps are eventually difficult and after you receive tokens, you cannot make any transactions out of it because most of them did not hit Cryptocurrency exchange until today. That's why I stopped joining airdrops and focus on my signature bounty campaign.
