If you set a very low miner fee when transferring BTC, the transfer will be pending for a long time.

If your BTC transfer is not confirmed within 48 hours, it will be marked as "Timeout". This status doesn't indicate a failed or cancelled transaction. Transactions on the Bitcoin network, once initiated, cannot be cancelled. You have two options in this situation:

  1. Wait patiently for the miner fees on the BTC network to decrease and your transaction to be packaged by miners
  2. Use a third-party paid BTC acceleration service

The acceleration operation is as follows:

  1. Click "Speed up" on the BTC wallet to launch CoinEx Explorer
  2. Enter the Tx ID of your transfer, then click "Estimate Price" to see the required fee for acceleration, choose a payment method, click "Confirm"and complete the payment. 
  3. After payment, you can stay on the page or return to the BTC wallet page to wait for the acceleration results.
