Setting keypool size in the conf file I used keypool=10000 in the conf file but bitcoin-cli -getinfo shows "keypoolsize":1000. Why?
keypoolsize only shows how many keys are currently in the keypool. It does not reflect the maximum size of the keypool. The keypool=&lt;n&gt; option does not automatically fill the keypool to that size, you will need to refill it by using keypoolrefill.

If after keypoolrefill you still do not see a larger keypool, then that means your bitcoin.conf file is either named incorrectly, located in the wrong location, or formatted incorrectly.
