selling my 2013 bitcoin wallet.dat file with nearly 29 bitcoins
You want someone to trust you, but you can't provide the same number in the title and the post? In any case, you cannot prove that it is your wallet - and even if you give it to someone as a gift, if you have set a long password consisting of random numbers, letters and special characters, there is no help (at least for now).
If you have at least some clues as to what the password consists of and how many characters it has, I suggest you try this service - the only legitimate one that I personally know exists.
