Sorry to come onto the end of your post but I am desperate, and I am in a similar predicament as you and hoping someone is able to HELP me please.
I have my own PC, its tweak the way I like it, very v fast and I have warned my Bro off it so many times. Bitcoins I've been following more or less from the start, lack of cash has prevented my making any serious cash but I understand its not just about that.
Well after using an online Wallet that's just announced its pulling the site as its been compromised, thankfully I just used the site this once and for a short stay with my Btc's which I sent to my Tablets Wallet, never really been that keen on the Tablets Wallet, and have been looking ages for 1 that I like, and at last I found what I classed as my perfect Wallet in Electrum.
I downloaded it, installed, and in meantime went and got myself a beer, came back to it up and running, Wow I thought, I like this. So I played around for a couple o minutes to familiarize myself with it, and Yes I thought, this is the 1 I'll use, so I scan the Wallets Addy with tablet and send them to Electrum Wallet without thinking, and Duh, the bombshell dropped as soon as I sent: I didn't recall getting the option to create a password or select a server on installing it etc.
And then it dawned on me, why did I not get this freaking option... and after 20 mins or so trying to guess its password etc. I stroll into my Bro's room asking him if he's used my PC lately, "not for a few months he added" So after a couple of slaps I got him to admit that he'd used my PC when sourcing a Wallet for himself. Turns out he'd already tried Electrum but had uninstalled; So when I came to install it, not realizing its for the 2nd time, obviously its defaulted to 1st install for passwords and seeds etc and now my bugger of a Bro cannot remember ANY of the info he entered, so I'm stuck with a nice Electrum software that is goner be my Wallet, showing just over 5 Bitcoins in and cannot retrieve them in anyway as I don't know the password.
Please if anyone can help and show me a way I can get around this. I'm so broke atm and selling these coins would make a big difference as you can imagine (I'm was hoping to put the cash towards our mums medical bills). I've thumped my Bro enough and I do also take a little responsibility for it, I should have been more alert when installing it
many many thanks in advance
regards Oinky
I recommend further brother beatings, followed by slow torture. Sooner or later, you will unlock that corner of his memory where that password is stored. Or he'll break and devolve into insanity and you'll have to have him institutionalized.
