I am facing a problem of long waiting unconfirmed transaction since yesterday. (Same problem with many people here). All of my wallet and transaction are Blockchain.info
But while I am waiting for confirming transaction, my destination wallet already got balance and I can do transfer from this wallet to another wallet.
I have 4 wallets (A, B, C, D)
The question are 1. why my B wallet got available balance and can transfer out? 2. what will happen to my B->D transaction?
