When Your Bitcoin Gets Stuck: The Ultimate Solution for 2025 Still 卡币

Have you ever experienced this awkwardness—your sent BTC hasn't been confirmed, and it looks like the mempool is as congested as a train station during the Spring Festival travel rush? This isn't about losing money; it's that your gas fee bid was too low and got pushed to the back.

Why is it stuck? To put it simply, there are two reasons:

1. Network congestion: The BTC block space limit is 4MB. When the market is booming, everyone is vying for confirmation, and miners prioritize packaging transactions with high gas fees. Your low-fee transaction has to patiently wait in line.

2. Setting the transaction fee too low: Some wallets calculate the fee inaccurately, or you manually set it too stingily, and miners just pass it with a glance—this is slower than waiting for watermark money.

Three tricks to immediately rescue your card currency:

Technique 1: RBF (Replace-By-Fee) The transaction hasn't been packed into a block yet? Resend it using RBF, this time with double the fee. The prerequisite is that your wallet supports it, and you need to enable the opt-in RBF option before sending the transaction. Simply put, it tells the Miner: “I want to increase the price for this transaction.”

Technique Two: CPFP (Child-Pays-For-Parent) Does the wallet not support RBF? No problem, use a child transaction to carry the parent transaction out. The method is to spend the output of the stuck transaction, and set a higher fee rate for the new transaction. Miners want to make money, so the two transactions will be packaged together, and your bad transaction will be rescued.

Technique Three: Transaction Accelerator Directly use the acceleration services of Mempool or ViaBTC. The minimum requirement is a fee of 0.1 mBTC/kb, with the free version limited to 100 transactions per hour. Alternatively, accelerate through the Mempool accelerator by paying with Lightning (the fastest speed).

How to check the transaction status?

Go to Mempool.space or any block explorer, paste your transaction ID. If it shows “unconfirmed” and there is no estimated block number - then congratulations, the gas fee is indeed too low.

How to avoid it next time?

Core recommendation: Set fees based on urgency.

• Not in a hurry? Just wait using the default fee rate recommended by the wallet.
• In a hurry? When the network is congested, raise the fee yourself; it's better to spend a little more money than to get stuck.
• Is it stuck? First, check if the wallet supports RBF or CPFP, choose one to use.

Don't worry, BTC won't disappear into thin air. In the worst-case scenario, if the transaction is abandoned from the mempool (usually within a few days), your coins will be returned to your wallet, and you can resend it. Just remember to be smart this time and set a higher gas fee.
