I have read that sometimes the QT wallet does not recognize your password even if it is written correctly, is this true? If you backup the wallet before you put a password and then again after you put one, can you later restore the non-password protected wallet if in the future QT stops accepting your correct password? I find this absolutely insane! Not even sure if it is 100% correct so please tell me if such a problem really exists with QT wallets. I still haven't put any CRDNC in my wallet as I wanna make sure I know exactly how to protect my coins if anything crazy happens.
