I have bitcoind running on windows and currently it's syncing the blockchain. Nevertheless, command getbalance always returns zero as value. Even if I seach for an address which has bitcoin.
E.g. C:\Program Files\Bitcoin\daemon>bitcoin-cli.exe getbalance "[address...]" 0.00000000
Why does it always return 0? I would like to get the address balance of a specific address. I used an address from blockchain.info which had a balance before the current downloaded block.
