WLFI's USD1 has been gaining momentum recently. The 7-day agreement revenue of WLFI on Defilama has risen to 8th place, with an annualized revenue of $112 million. Essentially, it is treasury bond. The reserve fund of USD 1 bought short-term US debt. Based on the current issuance of USD 4.6 billion and the short-term treasury bond interest rate of about 3.5%, it is highly consistent with the income data of Defilama. But this interest based model is almost over. The demand for holding coins for financial management has been squeezed to the point of seventy or eighty percent. Whether USD1 can break through the ceiling depends on whether the money can be truly used, rather than just sitting there and eating interest rate spreads. Binance has also realized this issue. The rules for the USD1 airdrop activity were just updated on July 3rd. Previously, holding USD1 was enough to receive airdrops, and there was also a bonus when it was deposited into a contract account. However, this is no longer possible. ⚠️ The core change of the new regulations is that in order to receive a 1.2x bonus on a contract or leveraged account, the minimum daily open interest amount on the USD1 contract trading pair must not be less than 300 USD1. Binance takes a snapshot every hour and judges based on the lowest value of the day. Unable to reach 300 USD1 but with open positions in the account, only 1 times the basic return can be obtained. Summary in one sentence: Only by using USD1 can you maximize your profits How to get a 1.2x bonus in the most hassle free way without delaying interest payments? The current most cost-effective path is Earn current interest+Futures 1.2x markup. Three specific steps. The first step is to deposit up to 2000 USD1 into financial management, with an annualized maximum of 8.5%, real-time interest calculation, and flexible deposit and withdrawal. Step 2, transfer the remaining USD1 to the contract account, select the BTCUD1 perpetual contract (0 hanging fee), set 1x leverage+position by position mode, open the position with a nominal value of ≥ 300 USD1, and then move on to maintain a daily open position of no less than 300. There is a detail worth noting: as long as the daily minimum open interest amount is met, all USD1 (including margin) in the contract account can enjoy a 1.2x bonus, not just the opening part. Step three, fund rate hedging. A position of 300 USD1, if the rate is maintained at 0.03%, would require a daily payment of approximately 0.28 USD. You can break down your position into 150 long and 150 short to offset the impact of price fluctuations and funding rates. The rate itself can be positive or negative, and the actual cost is subject to real-time. Calculate the general ledger. 2000 USD1 earns 8.5% annualized interest. The remaining portion will receive a 1.2-fold WLFI airdrop bonus, which will be enjoyed by all contract accounts with USD1. The combination of two returns results in a significantly higher annualized composite than pure holding or pure Earn. The shift in mindset from issuing coin subsidies to completing transactions for USD1 is quite obvious. The reason why USDT's position is strong is that it is the base currency of many exchanges. Only after USD1 enters trading can there be user stickiness, and it is very necessary to use it
