I found a key which begins with a 1 on my old computer (2013) in a text document and I have been unable to work out the process from here to get to the bitcoin if it exists.
I have downloaded Electrum and in the import Bitcoin Addresses menu typing my key in does not work and this is the info box:
WIF keys are typed in Electrum, based on script type.
A few examples:
p2pkh:KxZcY47uGp9a... -> 1DckmggQM...
p2wpkh-p2sh:KxZcY47uGp9a... -> 3NhNeZQXF...
p2wpkh:KxZcY47uGp9a... -> bc1q3fjfk...
I believe my key must be p2pkh but typing in "p2pkh:InsertMyKeyHere" does not work.
In this format p2pkh: X -> Y. Is Y an output or are they both inputs?
I have been unable to type anything into the box which "un-greys" the "Next" box.
Any help working out the process from here would be greatly appreciated.
Cheers
