My strategy with Airdrops is to always sell half of what I earn as soon as possible, because airdrops are most likely to dump. There will be people who got their share of the airdrop for low-to-no effort, and they'd dump at any price they see.
P.S. I have a few Airdrops I need referrals for, and I'll pay in HIVE for you to join if you're interested: https://inleo.io/threads/view/ahmadmanga/re-hivelist-33mf2qiug?referral=ahmadmanga
