What exactly is the U Card? Is it useful? Are there any pitfalls? Can it replace C2C?
Last time, I briefly introduced the U Card and found that many friends still had many questions and were quite interested, so this time I will write a slightly more comprehensive introduction for everyone. Introduction to the concept of the U Card The U Card, as the name suggests, is fully known as the 'USDT Card' or 'Crypto Card', which is a virtual or physical bank card that supports recharging with USDT (Tether, a stablecoin pegged to the US dollar at a 1:1 ratio). Essentially, it is a prepaid debit card issued overseas (usually in partnership with Visa, Mastercard, or UnionPay) that allows users to recharge with cryptocurrency (such as USDT) and use it directly for daily expenses, ATM withdrawals, or online payments without first converting USDT into fiat currency. (However, it is different from ordinary domestic bank cards and can be understood as an international credit card)

What exactly is a rebate? Why are so many people promoting it? Are there pitfalls? Can you make money? (Purely educational article)
A rebate is a major resource for you in the cryptocurrency space, allowing you to save money and make money. It's also the only chip you can negotiate with in front of KOLs! Read this article carefully and make good use of this chip! This article is written in a Q&A format! (Quick Q&A) What is a rebate? When you trade on an exchange, like Binance, the platform charges a 'fee' whether you are trading spots or contracts. This is how they make their profit, right? Well, spot trading is manageable, but contracts can be terrifying; the fee model for contracts is based on the amount of your position. For example, if you have a $1000 position with 100x leverage, that’s a $100,000 position. When you open and close a position, I remember the fee is around 0.15%. No matter if it’s spot or contract trading, if your trading volume is large, this fee can be quite scary.
