How to pay from a crypto exchange without losing money

Paying straight from an exchange is convenient, but exchanges deduct fees, list the same coin on several networks and sometimes hold withdrawals. Here is how to make sure the right amount arrives, on the right network, in time.

In short

  • Exchanges usually take their fee out of the amount: aim for the amount that must arrive.
  • Select exactly the network shown on the payment page — USDT on TRON (TRC-20) is the simplest.
  • The coin amount is locked for 30 minutes, or 45 for Bitcoin and Monero.
  • Something went wrong? Report it with the transaction ID — never send twice.

The three ways exchange payments go wrong

  • The fee comes out of the amount. Most exchanges deduct their withdrawal fee from the amount you type. You send 100 USDT, and 99 arrive.
  • The wrong network is selected. Exchanges list USDT and ETH on several networks, and a payment sent on the wrong one doesn’t reach your top-up.
  • The withdrawal is held. Exchanges may review withdrawals, process them in batches, or lock a newly added address for a day.

None of these has to cost you money. The steps below avoid all three.

Aim for the amount that must arrive

The payment page shows the exact amount to send, in the coin you chose. That is the amount that must arrive. In your exchange’s withdrawal form, raise the amount until the “you will receive” line matches it — the exchange’s fee then comes on top instead of out of your payment.

The price is fixed in dollars. The coin amount is locked for 30 minutes (45 for Bitcoin and Monero), and the address keeps being watched for a couple of hours after that, so a slow withdrawal is still picked up.

Step by step

  1. Create the top-up first from your account: choose the amount (from $30) and the coin. USDT on TRON (TRC-20) is the easiest from an exchange.
  2. Copy the address from the payment page. It belongs to this payment only; no memo or tag is needed.
  3. In the exchange, open Withdraw, select the same coin and exactly the network shown on the payment page.
  4. Paste the address and compare its first and last characters with the payment page.
  5. Enter the amount so that the amount received matches the one we show.
  6. Confirm with your exchange’s 2FA and keep the transaction ID (TxID).
  7. Follow the status on the payment page — it updates by itself, and you can close it. Your balance is credited, bonus included, as soon as the payment confirms.

Your exchange also charges its own withdrawal fee, which can be far higher than the network fee. Compare it before you choose: for most top-ups, USDT on TRON or SOL cost the least.

These five networks are the only ones we accept. USDT sent as ERC-20 or BEP-20, ETH sent on a layer 2, or bitcoin sent over Lightning never reach the payment — pick the network named on the payment page.

New address, new-address hold

Every top-up gets a fresh address. Some exchanges lock withdrawals to a newly added address for up to 24 hours, which is longer than the payment stays open. Check your exchange’s address settings before you start; if a lock applies, withdraw to your own wallet first and pay from there.

If something went wrong

  • Too little arrived: the payment page shows what was received and what is still missing. Send the rest to the same address while the payment is open. If it closes short, use “Report a problem” on the payment, with the TxID.
  • Too much arrived: use “Report a problem” on the payment, with the TxID. Once checked, the difference is added to your balance.
  • Wrong network or wrong token: don’t send again. Use “Report a problem” on the payment in your account, with the TxID. When the funds can technically be recovered, we guide you through it; some mistakes can’t be reversed.
  • Withdrawal stuck at the exchange: the delay is on the exchange’s side, and their support can tell you why. A payment that lands while the address is still watched is processed normally.

Top up once, and less often

If you plan to keep numbers for a while, top up once and let renewals run from your balance. You deal with exchange fees and delays once, not every month — and from $100, the top-up earns a bonus: +10% at $100, rising to +50% at $1,000.

Your balance never expires, and what you paid in can be refunded in crypto, minus the network fee (bonus credit excluded). See how payments work, or pay with Monero straight from your own wallet: how to pay with Monero.

Questions about this guide

Do I need a memo or a tag?

No. Every top-up has its own address, so payments are matched without a memo.

My exchange only offers USDT on Ethereum (ERC-20). Can I use it?

No — we accept USDT on TRON (TRC-20) only. Almost every exchange offers TRC-20; if yours doesn’t, pay with ETH on the Ethereum network, SOL, BTC or XMR instead.

What if the countdown ends while my withdrawal is pending?

The address keeps being watched for a couple of hours after the countdown, and a payment detected then is still processed. If it doesn’t appear, use “Report a problem” on the payment.

Can I pay part from my wallet and part from an exchange?

Yes, while the payment is open: send the rest to the same address, and everything that arrives counts towards the top-up.
