## [Credit freeze vs paid credit lock: what you can do for free](https://nosecrets.app/markdown/en/stories/credit-freeze-paid-lock-monitoring)

A security freeze is free. Paid monitoring and credit-lock bundles are different services, and none prevents every kind of identity theft.

Scope: United States · nationwide credit reporting companies

## [A fintech app says 'FDIC insured'. What is actually protected?](https://nosecrets.app/markdown/en/stories/fintech-app-fdic-insurance-limits)

Deposit insurance concerns an insured bank's failure. A nonbank app's bankruptcy, records and access problems are separate risks.

Scope: United States · nonbank apps placing customer funds at banks

## [Interest-free BNPL can still cost you money](https://nosecrets.app/markdown/en/stories/bnpl-interest-free-hidden-fees)

Installment dates, late fees and bank overdraft charges can matter more than the headline interest rate.

Scope: United States · buy now, pay later consumer guidance

## [Pay in local currency or home currency? Read the DCC offer](https://nosecrets.app/markdown/en/stories/travel-card-dynamic-currency-conversion)

Paying in your familiar currency can embed a merchant conversion markup. Your card issuer's separate fees still need checking.

Scope: Cross-border Visa card purchases and ATM currency-conversion offers

## ['Zero-fee' remittance: compare what the recipient gets](https://nosecrets.app/markdown/en/stories/remittance-zero-fee-exchange-rate)

The transfer fee is only one part of the comparison. Exchange rates and recipient-side deductions affect the result.

Scope: United States · covered consumer international remittance transfers

## [Discounted 'tainted USDT' is not a safe arbitrage opportunity](https://nosecrets.app/markdown/en/stories/discount-usdt-black-u-freeze-risk)

A completed transfer does not establish the funds' origin or guarantee that an address will remain usable.

Scope: USDT counterparties · issuer policy and a US enforcement example

## [A cheap top-up can work today and be reversed later](https://nosecrets.app/markdown/en/stories/discount-topups-revoked-game-gifts)

Steam documents gifts removed after fraud or payment disputes. Initial delivery is not the end of the payment chain.

Scope: Steam gifts · a concrete example of third-party top-up risk

## ['Pay to unlock your USDT' can be the second scam](https://nosecrets.app/markdown/en/stories/crypto-unlock-fee-recovery-scam)

Fake wallet approvals, invented release charges and guaranteed recovery pitches can turn one loss into several.

Scope: Crypto wallet and recovery scams · FBI public alerts
