I have downloaded litecoin code (version of 14 september,2014) and built it. so right now I have a wallet. i have account which's name is just "". then i connected my miner to my node. It solved the block and now I have a balance. ./litecoin-cli getbalance "" returns 150LTC , but as I can see, there're 3 addresses which belong to this account (""); why all of these 3 addresses have balance 0.000? how is it possible that account has a balance and not the addresses? Even if i type ./litecoin-cli getinfo it tells me that my balance is 0.0000 , but if i type ./litecoin-cli getbalance "" why does it return 150?
