estimatefee

estimatefee nblocks

DEPRECATED. Please use estimatesmartfee for more intelligent estimates. Estimates the approximate fee per kilobyte needed for a transaction to begin confirmation within nblocks blocks. Uses virtual transaction size of transaction as defined in BIP 141 (witness data is discounted).

Arguments:

1. nblocks (numeric, required)

Result: n (numeric) estimated fee-per-kilobyte

A negative value is returned if not enough transactions and blocks have been observed to make an estimate. -1 is always returned for nblocks == 1 as it is impossible to calculate a fee that is high enough to get reliably included in the next block.

Example:

bitcoin-cli estimatefee 6
