I heard about it somewhere, but no where found a complete step by step solution.
I've heard that for addresses in the same wallet, the transaction fees can be avoided. Is it a rumor ?
If no, then please help on how to attain it.
By wallet, I mean to say the wallet that is being used by bitcoind/litecoind or bitcoin-qt/litecoin-qt on a machine. (they usually use the wallet.dat)
