So with that I looked through my files and I found my Bitcoin key that starts with an "L" (51 characters ?)and I have a private key also that which starts with a "U" (103 characters?) I`m going to work on recovering my coins . Thank you .
The 51 characters that starts with 'L' looks promising but it should be 52 characters.
The other can't be a WIF private key nor a ECDSA private keys simply because of the starting character.
BTW, since your address starts with '3', you need to add "
p2wpkh-p2sh:" in front of the private key when importing to Electrum,
example:
p2wpkh-p2sh:L25aB3g4SpRxxDUyvNqD9rwsyjvULJ8DDHrvynQnm7TSJgxxxxxx
Without it, Electrum will derive legacy address that starts with '1' instead.
Update: I made another watch only wallet like you suggested, all the coins appeared in there.
I know the name of the bitcoin site now it`s bitcoinofficial dot org.
I tried to import btc address but it said its already in there. (Electrum watch only wallet)
I have public keys, private keys and Segwit for Bitcoin and address.
And I also have private key and bc address for Electrum for my named wallet.
I think I missed something but I`m just looking at a lot of information.
The default wallet has "seed" shaded grey, which means no seed.
I'll repeat my question above which you haven't answered yet: How did you create this watch only wallet? Did you go through the Electrum set up wizard and write down the seed phrase of 12 random words it showed you at some point? Or did you get a master public key (a long string of characters starting with "zpub") from somewhere else and use that to create the wallet? Or did you just import the addresses manually? Answering this is necessary before we can potentially work out how you can spend your coins.
Its not an Electrum generated address.
So where was it generated?
Wallet was generated at BitcoinOffical dot org.
The address starts with a "3"
