What is the profit percentage of a perpetual contract to cover the handling fee? I opened a 125x contract and earned 4% after closing the position. But I found that my assets still lost 9%. Was all the handling fee deducted?

It's already 2025, do you think the crypto world can change the fate of ordinary people?

Last year I spent the New Year in Shenzhen, and there were indeed a lot of A9s in the crypto world here, and quite a few have reached A9.5 in this wave.
If the market goes well this year, Shenzhen is expected to become the city with the most crypto + A10 in the country. The enthusiasm for making money here and the innovation capability are almost unmatched by other places: various crypto protocols from code design, media promotion, KOL marketing, capital investment, market-making + coordination, and trading on exchanges are all mature and integrated.
This wave of BRC20 has already put Shenzhen at the forefront, and if nothing unexpected happens, various innovative protocol levels will also be led by Shenzhen.
Every year in the crypto world, there are hundred-fold projects; in the first half of 2023 alone, there were hundred-fold coins: just catching one gives you a chance to break through class barriers.
ORDI (500 times)
KAS (100 times)
ETHS (700 times)
ORDI was created on March 8, when minting only required gas + fees of about 1-3, and now it has reached 1000U, an increase of about 500 times.
PEPE (1000 times)
#KAS+ (from last October to now, has yielded 100 times)
After Ethereum transitioned to POS last year, mining machines had nowhere to go and were unwilling to sell at low prices; KAS+ took on most of the miners. Its founder, Y, is also very impressive; look it up if you're interested.
In fact, you'll find that most of these hundred-fold projects are on small exchanges or haven't even gone on exchanges yet. The process of these air coins turning into valuable coins is the opportunity for retail investors to make money. Meme+ is exactly like this. If a project is inherently valuable, the first to enter are usually institutional investors, so retail investors have little chance.

Recently saw a question on another Q&A platform. A user with high leverage, trading at 125x, closed their position with a profit of 4%, but their assets still showed a loss of 8.5%?
Upon checking, all the losses were due to fees. Why is this? How can one earn more?

According to the platform's fee calculation formula, 'Position value × Fee rate = Fee', we can gather some information. If you use 100x leverage and only limit orders, your position must profit by at least 4% to make a gain. Similarly, for pure market orders, your position needs to profit by over 10% for you to earn.

The issue of fees is unavoidable for contract users. We must understand how it is calculated to have a clear idea about making money; relying on luck is the worst thing in trading.

So how can one earn more?
(For long-term traders, the fees may have already exceeded the principal.)

First, you need to understand the root cause: the 'fee rate'. Reducing your fee rate can significantly boost your profits. Therefore, you need to lower the fee rate or reduce fee payments. Below are specific methods I’ve outlined for you:

1. Hold platform BNB. In USDT-based contracts, you can enjoy a 10% discount on fees. This is effective for all users; you just need to transfer enough BNB to pay for a single fee into your contract account.

2. Upgrade your VIP level. This is related to the first point because increasing your VIP level requires not only higher trading volume but also holding a certain amount of BNB.

3. New user rebates. This is available to new users who fill in an invitation code upon registration. Rebates are a certain percentage of the actual fees incurred by the user, distinguishing it from the first two methods, as the first two focus on reducing the user's fee rate. (This is the most effective and simplest way to save money.)

If perpetual contracts are held without selling, or not sold, will there be any costs incurred?

In perpetual contracts, there is a funding rate
It is generally displayed in the upper right corner of the order book
By default, it is 0.01%, adjusted according to the market's long and short ratio
The funding rate is settled three times a day, at 0:00, 8:00, and 16:00
Positions held at the settlement time will be settled
If the funding rate is positive, holding long positions incurs costs, while short positions gain money
If the funding rate is negative, holding short positions incurs costs, while long positions gain money
The funding fee is given by the market participants who are long and short
The calculation method for the funding fee: position value × funding rate
If you plan to hold for the long term, the funding fee can also be a significant expense

Many brothers have asked me where to see the transaction fees, so I am here to answer for you.
Open the Binance APP -- Funds -- Contracts -- Today's Profit and Loss -- Funding Fees and Trading Fees.
You can see your transaction fees for the past year. 🤷
According to the platform's fee calculation formula, "Position Value × Fee Rate = Fee", you can get an idea that if you use 100x leverage for pure limit orders, your position must at least profit by over 4% to make a gain. Similarly, for pure market orders, your position must profit by over 10% for you to earn.
Let me give you an example:
If you use 900 U with 100x leverage to buy 1 Bitcoin worth 90,000 U, the position value at this time is 90,000 U.
The fee generated by placing a buy limit order is 90,000 × 0.02% = 18. You need to manually set the opening and closing positions for limit orders.
The fee generated by a market order is 90,000 × 0.05% = 45. The system automatically enters for market orders (the system will enter at the current best price).
The fee for one transaction (buy and sell) is either 36 or 90.
(The above is just an example, do not imitate!!!)
For those who trade contracts with large positions,
Your transaction fee expenditure may exceed your principal in just one month.
So you must enable commission rebates; you should recover the transaction fees that are due to you. If you don't enable rebates, all fees go to the market.
Different invitation codes have varying rebate ratios, methods, and times; even a 5% difference in rebates can lead to a few hundred to a few thousand U in larger trading volumes.
🔺 Fee rebates are mutually beneficial, but they are also not meant to deceive users who do not understand; we must severely crack down on those deceptive KOLs.

How to Buy BTC in the Cryptocurrency Market in 2025?

1. Choose an Exchange: Selecting a reputable cryptocurrency exchange is the first step in purchasing Bitcoin. There are many well-known exchanges in the market, such as Binance, OKX, etc. When choosing, consider factors such as the platform's reputation, security, transaction fees, and supported trading pairs.
2. Register and Verify Your Account: Creating an account on the chosen exchange typically requires providing a valid email address and setting a secure password. Some platforms may also require you to go through a verification process to ensure compliance with Anti-Money Laundering (AML) and Know Your Customer (KYC) regulations.
3. Deposit Funds: After registering and verifying your account, the next step is to deposit funds. Most platforms support various deposit methods, including bank transfers, credit cards, debit cards, and other cryptocurrencies. Once you choose a suitable method to deposit, you can start buying Bitcoin.

Detailed Explanation of Cryptocurrency Trading Fees: Why Are They So High? How to Save Money?
Cryptocurrency trading fees can be exorbitant, often causing headaches for investors. The reasons behind this are complex and not solely dependent on the amount of capital. This article will delve into the causes of high fees and provide money-saving strategies.
First, fees are directly related to the position market value. The larger the position, the higher the market value, and the fees paid will also be higher. This is related to the billing methods of many exchanges, which do not charge fees purely based on capital.
Second, the trading method also affects the fees. 'Market orders' (i.e., buying or selling directly) usually incur higher fees than 'limit orders' (setting a price and waiting for a trade). This is because 'market orders' consume market liquidity, and exchanges typically encourage 'limit orders' to maintain market depth, resulting in lower fees for 'limit orders.' Among ordinary users, the fee for 'market orders' can be as high as 0.05%, while 'limit orders' are only 0.02%.
Finally, utilizing the rebate mechanism of exchanges can effectively reduce fees. Some exchanges offer fee reductions to users, and this portion of the fee is returned to the user's account. This is unrelated to trading volume and profit or loss; as long as a trade is executed, a reduction can be obtained. Applying for a reduction usually requires registration through an invitation link. Before opting for a reduction plan, it is essential to carefully understand details such as the reduction rate, duration, and cycles, and to conduct verification work.
In summary, the fee calculation formula is: Position Size × Fee Rate = Fee; the rebate calculation formula is: Generated Fees × Reduction Rate. The rebate mechanism is applicable not only to spot trading but also to contract trading, providing investors with opportunities to reduce costs and increase profits. To save on trading costs, it is recommended that investors try to use limit orders and actively participate in the exchange's rebate programs.

How to download Binance?
1. There are two ways to download Binance
(1) For Android systems, you can directly download it from the official website, or download the installation package
You can search for Binance's official website on Google Chrome to download it, or download Binance from the Google Play Store, but the Google Play Store requires a VPN to change the node to one outside of the US region; here we recommend nodes from Taiwan and Hong Kong.
However, HarmonyOS can also download it, as long as it is not a fully-fledged HarmonyOS system, Huawei devices can download it.
(2) For Apple systems, you need to use a foreign region ID to download it. Change your foreign region ID in the App Store to download. Note that the US region ID downloads the US version, which cannot be used; it can only be used in the US.
2. Why is the downloaded version in English?
(1) It is possible that you downloaded the US version of Binance. You need to check if you have the US version. If you downloaded the US version, you need to redownload it using your own foreign region ID.

If you could go back to 1989, you would discover a person named David Chaum who invented the digital currency eCash, which is very similar to Bitcoin. You would be glad to have caught this opportunity early.

But the project collapsed in 1999.

If you could go back to 1996, you would find a person named Douglas Jackson who invented a digital currency called e-gold, which was 1:1 pegged to gold (much like today's USDT or USDC). You would be glad to have finally seized the opportunity.

But by 2009, the project went bankrupt under government pressure.

If you could go back to 2005, you would finally realize that all the technological components for digital currency were in place, and a person named Nick Szabo proposed the concept of Bit Gold, suggesting the introduction of a POW consensus mechanism to reward miners for discovering blocks. You would be glad that perseverance pays off, and you could finally participate.

But in the end, no suitable developers were found, and the project was stillborn.

If you could go back to 2008, you would meet an anonymous geek named Satoshi who said he wanted to invent a digital currency system called Bitcoin. Would you participate back then?

Now is neither too early nor too late; those who acted too early became martyrs, and those who acted too late became the ones taking over.

This time frame is just right, implying that some good products or technologies need not only strong consensus in explicit conditions but also a bit of luck in implicit conditions.

Bitcoin succeeded because of the right timing, geography, and people.

Why are contract transaction fees so expensive, and how can they be reduced?

Why do some users find that when trading contracts, even though the yield rate shows positive when closing positions, the total funds in the position actually decrease? In fact, the lost portion of funds has served as the transaction fee for this closing trade, which is collected by the exchange. Therefore, experienced contract traders often advise beginners to trade less frequently and observe more. Frequent contract trading not only affects one's mindset and lowers the win rate but also increases trading costs. The accumulated transaction fees over time can also amount to a significant sum.
We come to the exchange to make money; if we blindly trade without first understanding the exchange's fee rules, we are likely to suffer losses. Currently, the contract transaction fees on mainstream exchange platforms consist of two parts: contract trading fees and funding fees.
