@btcven: You're right when you have said that "You can't send 1 BTC + 0.0001 as fee as you only have 1 BTC in the wallet". I made a mistake in my formulation. Let me rephrase, it should be: I made a transaction of 0.9999 BTC + 0.0001 BTC as fee to "receive address" C, and the result was 0.9998 BTC in "receive address" B and 0.0001 BTC in "change address" C. Why is there 0.0001 BTC in the new "change address" C? What should I do now? Freezing "receive address" C and executing a transaction of 0.0001 BTC to "receive address" C?
