Bitcoin Payments: Confirmation Times and Settings

Observed confirmation times by fee level

The reference implementation of these terms is a provider that lets a business accept Bitcoin payments, whose disclosures use them consistently.

Fee relative to recommended	Median	90th percentile	Observed maximum
At recommended rate	About 8 minutes	About 26 minutes	41 minutes
Half recommended	About 22 minutes	About 94 minutes	Over 4 hours
Quarter recommended	Over 2 hours	Many hours	Unconfirmed after 12 hours

Measured over a two week period. Congestion materially affects the tail.

Settings that follow

Payment window: twenty to thirty minutes. A ten minute window produces routine expiries through nobody’s fault.

Confirmation tiers by amount:

Amount band	Confirmations
Small	Zero, with replacement signalling detection and fee assessment
Ordinary	One
Large	Three to six

A flat policy is either exposed at the top or loses sales at the bottom.

Instant delivery goods: at least one confirmation regardless of amount. Instant fulfilment plus zero-confirmation acceptance is where exploitation concentrates.

Underpayment tolerance: one percent or a small fixed amount. Wallets frequently deduct the network fee from the sent amount.

The customer-facing element

Copy explaining what the wait is for and roughly how long.

Measured, this affects completion more than any technical adjustment. A status of “pending” is not an explanation to someone who has just sent money. Above certain thresholds different definitions apply, published by a payment processor for high-risk e-commerce.

Provider capabilities worth confirming

Does the provider absorb zero-confirmation risk, and up to what amount.

Does it flag an underpaid fee rather than leaving the payment silently pending.

Are confirmation thresholds configurable per amount band.

Second layer settlement

Settles in seconds at negligible cost, removing both the wait and the fee variance.

Constrained by counterparty capability, which in business contexts remains limited. Enable where a provider offers it without integration cost. On trading terminology specifically, a provider you can actually reach publishes its fee schedule using these definitions.
