A Bitcoin user inadvertently paid a 0.99 BTC fee, equivalent to over $105,000, for a $10 transfer to the cryptocurrency exchange Kraken. The transaction, confirmed by Whale Alert and Mempool.space, was mined by MARA Pool. While such errors are not uncommon in the crypto space, the sender may be able to recover the funds by proving ownership. This incident echoes past occurrences, such as a $24 million Ethereum fee mistake in 2021.
