If you want to create fresh btc addresses (in bulk) you can use bitcoin core (Without syncing).
on the bitcoin.conf file just add this:
keypoolsize=10000
this will create 10k btc addresses.
Sounds great. Thank you very much!
But where is "
bitcoin.conf"? I'm running a Bitcoin Core on OSX... Sorry, I'm not good on these things
then you can dump this wallet and get these 10k address & priv keys.
I get that, thanks, but what do you mean with "
...& priv keys"?
Sorry I use windows, don't know Mac, but you can find it here:
https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_FileI need to correct something. it's not keypoolsiz, it's "keypool=10000"
When you dump your wallet it gives you all the created bitcoin addresses and private keys;
For instance:
#this dump created on the date 03.12.2015
1address1 5privatekey
1address2 5privkey2
1adddres3 5privkey3
Make sure that you import only the public addresses. You should keep the private keys private.
