Warden airdrop project has an interesting threshold—registering a new account requires a fee of 3U to participate. Whether this cost can be recovered becomes the core issue. Many participants are pondering how much return they can get from low-cost accounts, and the project's recent actions are indeed worth observing. Many people are betting that this is a worthwhile airdrop opportunity to participate in, but the initial investment plus uncertain expected returns require careful evaluation. For projects that require payment upfront to receive an airdrop, the risk of being countered is present, so one must weigh the pros and cons before deciding whether to participate.
