Don't just focus on eating melons~You should take a look at products that improve your financial efficiency~We come to the cryptocurrency circle to make money, not to polish your nails~! I recently looked at HTX's "Yu Bi Bao" and besides the "maximum 13% APY" on the official website, it actually solves a very practical problem in contract trading: Financial efficiency. Most contract traders, like me, keep a portion of margin in their accounts for the long term. You cannot say that this part of the money is "idle" because it has to bear the risk of position; But from the perspective of asset utilization, it has not generated additional income in the past. HTX launches Yubibao with the aim of reusing this portion of funds: The money will continue to be kept in the contract account as margin, while also bearing interest. No need to pledge, no need to lock up positions, and no need to transfer funds back and forth from trading accounts for financial management. Even in the account: ·Available margin ·Position occupancy margin ·Freeze the deposit for pending orders All of them can be included in effective asset accumulation statistics. This is actually equivalent to adding a second layer of income sources to trading funds. More importantly, I have examined the profit logic behind it, and it is not simply using high APY as a subsidy. Yu Yinbao mainly earns profits through Funding Rate Arbitrage: Spot long+perpetual short for Delta hedging, earning capital fees while minimizing directional risk as much as possible. This is a common type of Market Neutral strategy among professional trading institutions, but HTX has productized it. So I prefer to understand Yu Bibao as: A fund efficiency tool for trading accounts, not just a wealth management product. This event further connected trading and profits. According to Prime level and trading volume, higher APY and larger interest limits can be unlocked step by step, up to a maximum of 13% annualized. And there's also an interesting detail: For the same transaction amount, the interest bearing principal that TradFi assets can unlock under certain levels is three times that of regular contracts. This is actually encouraging users to put Crypto, TradFi, and fund management into the same account system. Another mechanism that I value more is the risk reserve fund. The funding rate is not always positive, and when the market enters a negative funding environment, the arbitrage strategy itself will also face costs. HTX sets up an independent risk reserve to buffer this portion of funding costs. So from the perspective of product design, its logic is relatively complete: Trading → Margin Deposit → Funds Generate Returns → Trading Volume Continues to Unlock Higher Returns. For people who trade all day long, I think this is more meaningful than 'taking a single sum of money out for financial management'. Because what is truly expensive is never just transaction fees. There is also capital lying in the account but not fully utilized. Everyone can come and apply, don't let the funds lie idle~I have already utilized the excess margin @justinsuntron @HTX_Molly @xiaojiucai_andy
