If you have USDT and want to wait for BTC to drop a bit before buying; if you already hold BTC and want to wait until it reaches your desired price before selling. During this waiting period, can you earn an extra reward? Binance dual currency investment revolves around this kind of demand.
But when you see a high annualized return, do not interpret it as “storing coins for a few days and receiving interest.” You simultaneously agree upon a future buying or selling price, and at maturity, you may exchange both principal and reward for another type of coin.
Dual Currency Investment: First, Understand the Two Words “Dual Currency”
Binance categorizes dual currency investments as “high-yield type,” summarized as:
Rewards depend on the settlement price, allowing participation in price direction judgment while earning returns.
This sentence captures the main point, but it should be supplemented: the settlement rules determine not only which coin the rewards are paid in, but both the principal and rewards may also be converted to another coin. It does not require you to deposit both types of coins at the same time, but rather to agree on two possible settlement assets.
For example, if you invest USDT to wait to buy BTC, at maturity, you may receive either USDT or BTC. The basis for judgment is the relationship between the settlement price and the target price, rather than your last-minute choice of which one to select.
From the user experience, it has a term and yield quotation, which may remind people of fixed-term wealth management; however, the assets, legal attributes, and protection mechanisms are different, and it cannot be treated like bank deposits that enjoy deposit insurance. According to the terms, rewards are calculated by Binance at the agreed APR, and you simultaneously undertake the obligation to buy and sell upon condition triggering. The extra reward can be understood as compensation for accepting this trading agreement, and should not be interpreted as pure lending interest.

Buying Low and Selling High: What Happens When the Target Price is Reached?
Buying low: You have USDT and hope to buy BTC at the agreed price. When the settlement price is lower than or equal to the target price, both the principal and rewards are exchanged for BTC at the target price; if it is higher than the target price, it is settled in USDT.
Selling high: You have BTC and are willing to sell at the agreed price. When the settlement price is higher than or equal to the target price, both the principal and rewards are exchanged for USDT at the target price; if it is lower than the target price, it is settled in BTC.
Here, “low” and “high” express the preset buying and selling direction, but do not guarantee that it will be more favorable than the market price at the time of settlement. If the price drops further, buying low may buy at a higher price; if the price rises higher, selling high may sell too early.
It also does not equate to ordinary limit orders: hitting the target price midway does not mean immediate execution. The public product page uses the average market price between 15:30 and 16:00 Beijing time on the settlement date as the settlement price, with settlement occurring at 16:00. Judgments must refer to this settlement criterion.
Calculating a Buying Low Account: There are Rewards, But Principal May Be Lost
The following are all teaching assumptions, not the current market situation or actual quotation: BTC subscription price is 100,000 USDT; invest 1,000 USDT; low buying target price is 95,000 USDT; term is 7 days; APR is 36.5%; turn off automatic reinvestment.
According to the public terms, rewards accumulate from the subscription date; the specific number of interest days is subject to the period stated in the order. The following assumes the order completes interest calculations for 7 days.
Term yield = 36.5% × 7 ÷ 365 = 0.007, which is 0.7%. The reward is 1,000 × 0.007 = 7 USDT. The 36.5% is annualized and does not represent earning 36.5% in 7 days.
The official FAQ requires truncating the decimal form of the above term yield to four decimal places. In this example, 0.0070 is not affected; changing to a different set of parameters may lead to differences, and it should comply with the order's coin precision rules.

The last scenario is the most notable: assuming it can be valued at 85,000 USDT, these BTC are only worth about 901 USDT. Compared to the invested 1,000 USDT, the paper loss is about 99 USDT, approximately a 9.9% loss. The 7 USDT reward is already included in the result and cannot offset the price drop.
The above does not account for subsequent selling fees, slippage, taxes, and the effects of USDT's decoupling; 901 USDT is a valuation, not a guaranteed transaction amount. The key to buying low is not “can I receive 7 USDT,” but “if it drops to 85,000, will I still accept receiving coins at 95,000?”

Calculating a Selling High Account: More Coins Do Not Equal Asset Appreciation
Assuming the BTC subscription price is still 100,000 USDT, invest 0.01 BTC, with a high selling target price of 105,000 USDT, using the same term and APR as the previous example. The reward is 0.00007 BTC, leading to a total of 0.01007 BTC including principal and rewards.

When it rises to 115,000, if the original 0.01 BTC was held continuously, its valuation would be 1,150 USDT, which is 92.65 USDT more than the high selling settlement amount. This is a relative minor gain compared to holding onto the coins, and does not equate to a loss relative to the valuation at the time of subscription.
When it drops to 80,000, although the amount of BTC increases, when measured in USDT, it still shows significant shrinkage. When evaluating results, it is essential to look at how many coins are returned, their value, and how this compares to the original plan.
How to Operate: First Choose a Price You Are Willing to Execute, Then Look at the Annualized Return
Following the explanation order of the Launchpad “Product Overview → Operating Path → Reference Understanding,” we can break down the subscription into four steps:
- Confirm Eligibility to Participate. Log into your account, complete the necessary identity verification and the risk acknowledgment required on the page; region, account eligibility, supported trading pairs, and minimum amounts are subject to the actual available page.
- Find Dual Currency Investment. Access through Binance Wealth Management or open the official product page, select trading pairs and the low buy/high sell direction. The menu may show “High Yield” or “Advanced Wealth Management.”
- Verify the Outcomes. Record the invested assets, target price, duration, and rewards, and calculate what you would receive in both scenarios of triggering and not triggering the currency exchange.
- Confirm and Track the Order. Read the applicable terms, verify the automatic reinvestment options; after subscription, check the settlement results in your wealth management holdings or history.
After subscribing to ordinary dual currency investments, you cannot edit, cancel, or redeem early before settlement. Temporary needs for rent, tuition, and emergency funds are not suitable for investing in products that cannot be exited at will and may involve currency conversion.

Fees and Automatic Reinvestment: Do Not Just Focus on the Reward Numbers
According to Binance's official introduction, there are no trading fees charged when a low buy/high sell is triggered. But this does not mean the entire process is cost-free: preparing subscription assets, exchanging back for the original currency upon maturity, withdrawals, and other stages may still involve fees, price spreads, or network fees; exchanging at a target price unfavorable to oneself would also affect the final result.
Automatic reinvestment allows matured assets to enter the next product. Whether to continue the original direction, or to participate in the reverse after currency conversion, depends on the selected plan; it is not a tool for automatically identifying the best buying and selling points. The next period's APR cannot be guaranteed based on the current period, and turning off reinvestment does not equate to a preemptive recovery of the current principal. If you are not familiar with the settlement process, it is advisable to turn off reinvestment first and observe the results completely once.
This verification also found inconsistencies in the official page descriptions: the product page and FAQ have different settlement weeks, some pages use the APY label while the terms and FAQ use APR; there are also differences in the names of the automatic reinvestment plans. This article's examples calculate based on single period APR, without compound interest, and do not guarantee specific purchase days each week. It is essential to check orders against applicable terms, and consult official customer service for clarifications on any conflicts.
Under What Circumstances is It Worth Continuing to Understand?
If you already have a clear buying or selling plan, accept trading at the target price, and can bear fluctuations during the lock-in period, dual currency investment is worth studying as an execution method. Its appeal lies in adding rewards to the pre-set trading plans.
If you only want to earn interest on stablecoins, are unable to accept conversion to BTC, or are unwilling to sell BTC regardless of how high it goes, then no matter how high the annualized return is, it won't alleviate this mismatch. Additionally, risks of the custodial platform and the risks of stablecoin decoupling will not disappear due to a short term.
Before subscribing, try to answer a full sentence: “If I receive another type of coin at maturity and the price is less favorable than it is now, I still accept this outcome.” If you cannot answer this, calculate both outcomes clearly before deciding whether to participate.
