When I call estimatefee 1 in testnet it returns: -1

According to docs:

If the node doesn’t have enough information to make an estimate, the value -1 will be returned

But on my bitcoin-cli getblockchaininfo, my verificationprogress is: 0.9999960537430175

What am I missing?

  • Downvoter why? I already said that I know the reason? Pathetic! – truongnm Jan 7 '19 at 2:56

From the doc:

-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


  • But my node is running quite long and my verificationprogress is: 0.9999960537430175 – truongnm Jan 4 '19 at 3:39
  • No, it means for "estimatefee N", N must be larger than one, or it'll return -1. – MCCCS Jan 4 '19 at 4:34
  • Of course I ran with N larger than one, but no matter what number I entered, I get the same returned result – truongnm Jan 4 '19 at 4:57
  • Just get this error again after I restart my PC – truongnm Jan 24 '19 at 8:30

Seem that after I restart my PC then things worked!

  • I just get this error again and restart my PC doesn't work! – truongnm Jan 24 '19 at 7:20
