Hi Guys, first time poster here.
I have been buying bitcoins for a few months now but only small transactions.
I bought £170 worth earlier (.353 btc)
Copied the electrum receiving address and pasted it into bitbargains send address.
Did they send the coins? Is the transaction confirmed? Can you post the transaction id?
It has been several hours and nothing has come into my account, i checked the receiving address on electrum and the coins are in a watch only wallet. (I dont believe it is mine)
So you are watching someone elses address (why?) and send coins there? (why??)
I have no idea how this happened and i am extremely worried. Can anyone advise on what i can do please

i can provide all proof that the coins were purchased by me ( appears on my bank statement, show my account on bitbargain etc.)
i just need to know how to get them from this watch only wallet into my own wallet.
You cant. A watch only wallet is one - as the word says - where you watch only, you cant spend. Its missing the crucial part (the private key). Electrum does not just generate these wallets, you have to specficially create it. How did you create the wallet exactly?
