Frequently Asked Questions

USDT is a stablecoin pegged to the value of one US dollar. Unlike Bitcoin or Ethereum, its price barely fluctuates, making it well suited for payments and transfers. At a CoinBypass (coin top-up service), you can top up USDT with Korean won and use it for payments.

A service that lets you top up crypto assets such as USDT using Korean won is commonly called a CoinBypass or coin top-up service. Once you deposit, it sends USDT to the wallet address you specify. It is safest to use providers that transparently disclose their rates and fees.

We generally recommend the TRC20 (Tron) network, which is fast and has low fees. The receiving wallet's supported network and the sending network must match exactly; a mismatch can result in lost assets.

The USDT rate is basically the exchange rate plus the top-up service's margin (spread). It varies by provider, so check the real-time rate and fees before topping up.

Simply send the displayed amount of USDT to the wallet address provided by the merchant, and the payment is complete. Always verify the network and address before sending, and keep the TXID (transaction hash) generated after the transfer.

On the TRC20 network, block confirmation usually completes within a few dozen seconds. It may be slightly delayed depending on network congestion.

Blockchain transfers are irreversible, so once sent they cannot be canceled or refunded. That is why verifying the address, network, and amount before sending is the most important step. For an address you are transacting with for the first time, we recommend a small test transfer.

Some merchants support other stablecoins such as USDC. However, BTC and ETH are not recommended for payments due to price volatility and fees. Check which coins the merchant supports first.

Many overseas services are blocked for domestic cards and bank accounts. Because coin payments do not go through card companies or banks, they offer an alternative for bypassing such regional or industry restrictions.

They are only possible if the merchant supports cryptocurrency payments. Where it is not supported, you should consider other alternative payment methods such as overseas virtual cards.

Asset loss due to network mismatch, and fraudulent providers. Use only trustworthy top-up services and merchants, and avoid places that advertise abnormally favorable terms.

Holding and trading crypto assets is itself legal. However, depending on the transaction size, you may have an obligation to report income or the source of funds. For specifics, consult a tax or legal professional.

Never share your seed phrase (recovery phrase) with anyone. If this phrase is exposed, all of your wallet assets can be stolen. As a rule, store it safely offline.

Blockchain transfers cannot be reversed. If you send to a nonexistent address or an address on a different network, recovery is practically impossible. Always double-check the address and network before sending.
