Ever anxiously check your Bitcoin wallet, wondering why your transaction hasn’t confirmed yet? You’re not alone—unconfirmed transactions can be frustrating, especially when you don’t know how long the wait will be.

This guide breaks down what ETA really means, what affects it, and how to speed things up.

Let’s dive in!

What Does “Unconfirmed Bitcoin Transaction ETA” Mean?

An unconfirmed Bitcoin transaction is one that’s been broadcast to the network but hasn’t yet been included in a mined block.

The ETA is an estimate of how long it may take for miners to confirm it and add it to the blockchain.

One confirmation gets it started—six are typically needed for finality. Until then, your transaction is in limbo.

Why Do Transactions Remain Unconfirmed?

Bitcoin’s decentralized network relies on miners to validate transactions—but several key factors can delay yours and increase your ETA:

Transaction fees: Higher fees incentivize miners to confirm your transaction faster. Low fees may leave it stuck in the mempool (Bitcoin’s waiting area).

Network congestion: When many users send Bitcoin at once, the mempool gets crowded. Low-fee transactions often get pushed to the back.

Transaction size: Fees are based on size, measured in sats/vbyte. Larger transactions cost more to confirm. If your fee doesn’t match, it may get delayed.

Mining pool variability: Different pools have varying hash rates, which can affect how quickly your transaction is picked up.
