I updated the bitcoin node to version to 140200 on top of which one of my applications was running. There wasn't any issue with the flow of the application estimatefee RPC I get -1 for no matter what I give as the number of blocks. Also the alternate fee api estimatesmartfee returns negative values. When I execute the same api on a node with version 140100 it gives me a positive result How do I resolve this ?

-1 means "not enough information for an accurate estimation".

Try with a higher confirmation target.

  • I also thought it returns -1 when the block target is out of range (limits = 2-20) – Danny Brewster Sep 2 '17 at 8:00
  • i tried all numbers till 250 block numbers. Still it did not work. – Shabahat M. Ayubi Sep 2 '17 at 11:59
  • How long has your node been running? – Pieter Wuille Sep 2 '17 at 19:08
