Looking at the discussions in the forum, there are indeed some details about this round of airdrop that are worth clarifying.

Let's start with the most critical numbers: a total of USD equivalent WLFI tokens will be distributed over 4 weeks, with @E1@ USD equivalent each week. The first round runs from January 23 to January 30, and the subsequent three rounds are all distributed on Fridays, spanning the entire cycle until February 20.

The reward structure is quite interesting. As long as you hold @E2@ USD in a major exchange, whether in spot accounts or margin/contract accounts, you can participate in the airdrop share. But here’s a key advantage — USD used as collateral in contract or margin accounts can enjoy a 1.2x reward bonus. In other words, with the same 100-dollar investment, holding in a contract account can earn 20% more rewards than in a spot account. Over four airdrops, this effectively means an extra portion of gains.

The timing factor is actually especially important and often overlooked. The distribution rule is: daily eligible balance = the minimum USD1 balance snapshot taken each hour of that day. This means you need to maintain a stable position throughout the entire billing cycle; you can't just hold at the last minute. Starting from 8:00 on January 23, snapshots are taken every hour, directly affecting how much reward you can ultimately receive.

From an investment perspective, transferring USD1 into a contract account as collateral is indeed more cost-effective — the same principal automatically yields 20% higher returns. Rewards are credited before 18:00 (UTC) every Friday and can be checked in the distribution history. This mechanism is quite user-friendly, but the prerequisite is that you understand how the timing snapshots work, so you don't miss the billing cycle.
