So after I encrypt may wallet on Bt-qt
if I wanted to use and old un encrypted wallet why would this not work?
I thought BitCoin qt was just a window on the BlockChain, so you could still use your address using you private key?
Does encrypting a my wallet stop me look at those address and using them say from blockchain.info wallet
if I installed a new copy of Bitcoin qt then could I use the old non encrypted wallet
exactly what is Bitocin QT doing that can stop me using my old wallet elsewhere??? it must be doing something to the blockchain right??? or else how would it know???
