1. The Hidden Cost of Inaction

Every dollar sitting idle in your wallet has an opportunity cost. With WEEX’s Auto Earn “200U Incremental Campaign” (April 16–30, 2026), failing to move idle USDT into a yield-bearing position effectively means leaving free yield on the table. Unlike standard staking, this event offers a bonus marginal return on every 200U increase.

2. The Math of Marginal Gains

Standard Auto Earn provides a baseline APR. This campaign adds a tiered bonus on top:

  • Bonus Rate: 0.5% (1U per 200U) on net new deposits.
  • Efficient Cap: The highest efficiency is reached at a net increase of 100,000U, yielding a maximum bonus of 500U.
  • Rounding Logic: The system uses floor rounding (e.g., 350U counts as 200U), so precise capital allocation matters.

100,000UBase Yield500U (capped)0.005

4. Avoiding the "Rounding Trap"

The reward is calculated as (Net Increase ÷ 200) × 1U, rounded down.

  • Example A: 350U increase → 1U reward (the remaining 150U yields no marginal bonus).
  • Example B: 400U increase → 2U reward. Strategy: Consolidate your top-ups into multiples of 200U to avoid losing the bonus on residual balances.

5. Ranking Reward as an Upside Option

The leaderboard prize is not guaranteed but offers high upside for large participants:

  • Top 1: 200U (equivalent to an extra 0.2% on a 100,000U position)
  • Top 2-10: 50U
  • Top 11-100: 10U

6. FAQ for Rational Actors

Q: If I need to withdraw mid-event, should I still participate?

A: Only if your net increase remains ≥200U after accounting for the withdrawal. Otherwise, the marginal bonus drops to zero.

Q: Is the 500U cap per transaction or per user?

A: Per user. Any net increase beyond 100,000U does not earn additional bonus.

Q: How does rounding affect me if I deposit exactly 200U?

A: 200U → exactly 1U reward. No loss.
