USDT, as the main circulation medium in the cryptocurrency market, the safety of the withdrawal process is directly related to asset security. Based on common risks and practical experience, this prevention guide is organized, emphasizing the following key points:
1. Wallet selection: Build a solid defense from the source.
Prioritize using mainstream wallets verified by the market (such as MetaMask, Trust Wallet, etc.), download from official websites, and refuse third-party links or unknown installation packages — fake wallets often impersonate interfaces, and once you input your private key, assets can be stolen in seconds.
Beware of "niche high-yield wallets" gimmicks; these tools often hide backdoors, appearing convenient but are actually traps for asset theft.
2. Beware of phishing: Don't let your "fingers" take away assets.
Do not click on unknown links, pop-up ads, or "withdrawal channels" in social media private messages. Phishing sites will impersonate exchange or wallet interfaces; entering account passwords is equivalent to handing over your assets.
Manually enter the official website address or use a trusted bookmark to access it, avoiding redirection through search engines — scammers often buy keyword ads to place fake websites on the homepage.
3. Multi-signature and authorization: Don't be careless with permission management.
Do not enable multi-signature wallets unless necessary; if used, be sure to confirm the trustworthiness of each signer. Malicious multi-signature could lead to "your coins, your say doesn't count," and you may get stuck when trying to transfer.
When authorizing smart contracts, clearly understand "allowed spending amount" and "authorization period," and only give necessary permissions. Revoking the authorization in your wallet after use (tools like revoke.cash can be used) to avoid long-term "implicit authorization."
4. Private key management: This is your "lifeline of assets."
Private keys and recovery phrases must never be stored in phone albums, cloud notes, or WeChat files; it is best to write them by hand in a physical notebook and lock them in a safe place. Remember: whoever holds the private key owns the assets.
Don't say "acquaintance"; even family members and partners should not share private keys. In the crypto world, trust ≠ security; a single leak could lead to complete loss.
5. Airdrops and cashing out: Risk control is hidden in the details.
Sudden "USDT airdrops" are mostly scams; those requesting to input private keys or transfer "activation fees" are 100% scams. Legitimate airdrops will not ask for this information.
Withdraw cash to real-name merchants, prioritize platform-guaranteed transactions, and avoid private point-to-point transfers — unfamiliar merchants may use "account frozen" or "funds abnormal" as excuses to default.
6. Bank cards and timing: Avoid the risk of fund freezing.
Use a dedicated card for withdrawals: Do not use salary cards or daily spending cards to receive USDT cash-out funds. Open a separate bank card specifically for cryptocurrency deposits and withdrawals, so that even if risk control is triggered, it does not affect other accounts.
Choose the right time: Trading is more secure during workdays from 9:00 to 17:00. Frequent large transactions at night or early morning can easily trigger bank risk control (the system may identify it as "abnormal transactions"), leading to card freezes.
7. Tools and awareness: Security is a dynamic defense line.
Use wallets with risk interception features (such as imToken's security detection) that can automatically identify malicious contracts and phishing addresses.
Stay updated on the latest scam methods; cryptocurrency scams are constantly evolving. The more you learn, the less likely you are to be scammed.
The core principle of USDT withdrawal: "Be a little suspicious, be a little troublesome, and you will be a little safer." There is no "regret medicine" in the crypto world; taking 3 seconds to think about the risks before each operation is much more useful than regretting afterwards.
