250 sats at the hour rate
For 250 vbytes at 1 sat/vB. Compare all four source priorities below; the hour target is not a guarantee.
| Source priority | sat/vB | Total sats |
|---|---|---|
| Fastest | 3 | 750 |
| About 30 minutes | 1 | 250 |
| About 1 hour | 1 | 250 |
| Economy / flexible | 1 | 250 |
Fee = rate × virtual size, rounded up to a whole satoshi. Confirmation times are source targets, not guarantees.
No fee gap between the hour and economy rates. This is a cost comparison, not a prediction that waiting will save money.
