Bitcoin User Accidentally Hands Over $105,000 Fee on $10 Transaction

On Monday, a bitcoin user managed to send nearly an entire coin to miners by mistake—sending a 0.99 BTC fee on a simple $10 transfer to Kraken.

The $10 That Cost a Fortune

With the average high-priority bitcoin transaction fee sitting near $0.30 today, this unlucky user shelled out roughly 222,602 times more than necessary.

Whale Alert flagged the blooper on X, noting, “A fee of 0.99 BTC has just been paid for a single transaction to Kraken.” Mempool.space pegged the cost at 99,989,964 sats for that modest $10 transfer, and Arkham Intelligence’s platform confirms the $10 landed in a Kraken deposit wallet.

The BTC transfer in question. Mishaps like this typically stem from wallet settings that let users manually input fees or total outputs—leaving plenty of room for human error. If the change or recipient fields aren’t configured correctly, the network gleefully pockets the excess.

Sometimes the wallet’s fee estimator itself fumbles. The transaction ended up mined by MARA Pool, which means the miner bagged the windfall—but they could play nice and return it. Of course, the sender might need to prove ownership of the funds first—because nobody’s giving back a bitcoin-sized “oops” without some proof.

While a 1 BTC fee is painful, it’s far from the record. The crown for costliest mistake still belongs to a November 2023 transaction that burned through 83.65 BTC—worth about $3.1 million at the time.

Blunders like this aren’t exclusive to Bitcoin’s chain. In 2021, Bitfinex famously fat-fingered a $24 million ethereum transaction fee before the miner graciously refunded most of it. Bottom line: blockchain doesn’t forgive typos, but sometimes, the miners do.
