Have you ever come across ads claiming you can purchase phone or gas cards at low prices and resell them elsewhere for a profit? While this approach appears simple, it's often a well-crafted scam.
Typical techniques in these scams include:
Luring Victims with High Returns
Scammers bait users with promises of high returns, directing them to specific addresses. Once funds are transferred, users face a series of obstacles. Fraudsters often entice investors with claims of "easy money," only to present complicated terms after the fact.
Imposing Extra Requirements
Scammers may demand additional payments from users, such as deposits or activation fees, insisting these are "routine procedures." In reality, these are integral parts of the scam. If users refuse, not only do they lose potential profits, but their principal is also withheld. This method exemplifies the step-by-step approach scammers use to drain victims' funds.
Fake Cards or Cutting Off Contact
Even after users pay extra fees, the outcome is rarely positive. Scammers may supply counterfeit cards or simply disappear, resulting in total loss of funds. They frequently operate multiple accounts to evade tracking.
After one user submitted a withdrawal request, the scammer demanded a 200 USDT deposit. When the user refused and asked for a refund, the scammer denied the request.

Here, the scammer first creates the appearance of a successful transaction to gain the user's trust, then demands further payments. While "deposit" may sound legitimate, it's a common scam tactic. Reputable trading platforms never request post-transaction deposits.
In another case, the user was asked to pay a 200USDT activation fee after withdrawal. Similarly, when the user refused, the scammer cited "system procedures" to justify denying the refund.
This case follows the same pattern as the previous example, but under the guise of an "activation fee." Scammers use industry jargon to make their operations seem legitimate. However, trusted platforms never spring extra charges on users during withdrawals.
Most scams share similar patterns, and vigilant observation can help you avoid falling prey. Leading exchanges advise users to keep these four tips in mind:
Be Cautious of Private Messages
If you receive unsolicited private messages from strangers on Telegram, IM, WeChat, or other social platforms, remain vigilant. Don't place your trust easily, and block repeat harassers. Genuine platforms will never contact users individually outside official channels.
Don't Take Profit-Driven Claims at Face Value
Private transactions are highly risky. Avoid trusting offers to buy or sell digital assets via virtual top-up card trades promoted on social platforms at high prices or deep discounts. Be especially alert to "high return" schemes—most investors drawn in by such promises have suffered major losses.
Risks of Off-Platform Deals
Major exchanges strongly discourage private transactions outside their platforms. Such trades don't follow official procedures, and the platform can't help you if you're scammed. Always use official channels—these offer escrow services and dispute resolution systems to protect users.
Take Swift Action to Limit Losses
If you realize you've been scammed, act fast to minimize your losses. Save all chat and transaction records, and contact the official platform's customer support team immediately. Acting quickly is crucial. If necessary, report the incident to law enforcement. Preserving evidence is vital for any future legal action.
Scam methods include fake projects, Ponzi schemes, and fraudulent wallets. High-yield traps are marked by unrealistic return promises, aggressive solicitation, and lack of transparency. Always verify official information, check reviews, and scrutinize contract details.
Confirm the platform's legitimacy and avoid those promising high returns. Verify regulatory compliance, and be wary of unsolicited profit offers. Always conduct thorough research and stick to reputable projects.
If you've been scammed, immediately call the government's anti-fraud hotline at 165. Save all transaction records and cease contact with the scammer. Respond quickly; it's critical.
The cryptocurrency sector lacks sufficient regulation, with many fake projects and weak investor information security. Scams and Ponzi schemes are widespread, and fraudulent project packaging drives high investment fraud risks. High volatility is also a core characteristic.
A reputable platform should hold a valid operating license, feature advanced security protocols, ensure transaction transparency, segregate user assets, provide responsive customer support, and be subject to system audits.
High returns and tiered rewards are unsustainable—they lure investors while quickly draining funds. Watch out especially for network marketing models offering unusually high yields.
