Bitcoin user accidentally sent $60,000 in fees—Don’t make the same mistake
RBF lets you resend unconfirmed transactions with higher fees, but it requires a clear understanding of fee units, wallet behavior and transaction structure.
A misunderstanding of fee units led to an accidental overpayment worth more than $60,000 during a replace-by-fee transaction.
The user confused sat/vB (fee per byte) with total satoshis, leading to an extreme overpayment.
RBF replaces a transaction with a higher-fee version, while CPFP adds a new transaction to boost the original; each has different use cases and risks.
