Hello, this is CoinUs.

This guide is about Bitcoin withdrawal fee.

* CoinUs is a decentralized wallet, and the withdrawal fee is used only for fees on the network.

(No fees paid to CoinUs)

• Bitcoin Network Fee = Fee per byte (BTC/byte) * Transaction size (byte)

Fee per byte (BTC/byte)

Since the Transaction Fee is a fixed value, it is the fee per size that determines the actual network processing speed.

The higher the fee, the faster it is sent, and the lower it is, the slower it is processed.

If the fee is too low, it will only stay in the Mempool (block waiting state) and may not transfer.

In the case of CoinUs, you can reliably withdraw assets through the most optimized network fee in the current network we suggest.

If you want to modify a lower or higher fee than the fee suggested by CoinUs, you can always adjust your own settings.

Transaction size (byte)

Bitcoin is connected to one address by multiple UTXOs, so the actual holding quantity is the sum of the quantity recorded in each UTXO.

So, according to the amount of withdrawal, the amount of UTXO is imported, and the transaction size is determined accordingly, and this cannot be modified.

If you enter the withdrawal address and quantity in CoinUs,

you do not need to set it up because you can see the size automatically.

Thank you.
