There are many exchanges that include contract sections, including coin-based and U-based. Many people are not sure which one is better. In fact, there is no good or bad, only whether it is suitable or not.
"Currency standard" refers to the corresponding underlying products used for position opening and final delivery. For example, if you want to go long or short BTC, you need to deposit BTC into the contract account, and the final loss or profit will also be settled in BTC.
Coin-based contracts refer to contracts made with currencies other than USDT, with currencies used as margin. Taking Bitcoin as an example, coin-based contracts are contracts that use Bitcoin to earn Bitcoin. The profit and loss settlement during the transaction process are all settled in Bitcoin, and the specific profit needs to be calculated based on the rise and fall of the value of the currency itself.
Or you can understand it this way: the corresponding underlying products are used for opening positions and final delivery. For example, if you want to go long or short BTC, you need to deposit BTC into the contract account, and the final loss or profit will also be settled in BTC.
The U standard uses USDT as margin, and the profits and losses of the contracts are settled in USDT.
Or understand it this way, "U standard" means that USDT is used as the circulation certificate for opening positions and final delivery. No matter whether you are long or short BTC or ETH and other currencies, you need to deposit USDT into the contract account, and the final loss or profit will be settled in USDT.
So how do you choose currency standard or U standard?
I think: when going long, it is more beneficial to choose the currency standard. When going short, you should choose the U standard.
When the market is bullish, choose to go long on the coin basis. The coins pledged in the contract and the coins earned are rising, and the value of the coins themselves is also rising. Therefore, coin-based contracts are suitable for use in a bull market, while in a bear market, due to the depreciation of the coins, hedging or even losses may occur. When the market is bearish, choose to go short on the U basis. Although the player's coins will depreciate to a certain extent, since USDT is a relatively stable coin, the U earned will not depreciate. Whether the player's coins themselves depreciate has little effect on profits and losses. Therefore, using the U-based contract in a bear market will bring more profits. For players who cannot distinguish between bear and bull markets, the U-based contract is a safer choice.
The same is true for friends who choose leverage. Using U or coins as collateral is the same as the above situation. When bullish, you can use coins as collateral, because the rise is not only profitable because you choose the right direction, but also because the collateral coins bring profits because of the rise. This is the operation method of maximizing benefits.
Similarly, using U as collateral is a safer choice. Whether you choose right or wrong, it will not affect the actual value of your collateral U.
Let’s talk about the difference between full position and position by position.
In the full-position mode, all available balances in your leverage or contract account will be used as margin for your position. Full-position margin, also known as "cross-period margin", means using all available balances to avoid forced liquidation. Any other positions that have realized profits can help increase margin on losing positions. In the full-position mode, traders have a lower risk of forced liquidation of their positions.
In isolated position mode, the margin locked when the initial order is placed is the maximum loss of this position. When a position is forced to close, none of your available balance will be used to increase the margin of this position. By isolating the margin used for a position, you can limit the loss of this position to the initial margin amount, which will help you when your short-term speculative trading strategy fails.
In the full-position mode, the user's position margin will change with price changes. In the position-by-position mode, the margin required when opening a position will remain fixed. In general, the full-position mode is suitable for hedging traders, while the position-by-position mode is suitable for short-term investors to better implement risk control strategies.
