This is the top line of my wallet: Electrum 4.3.4 - 1N8vh... [standard]
All of this is normal, except for that "1N8vh..." is at the place where your wallet's name is. That means it is actually the name of your wallet, and that should
not be a Bitcoin address.
Did you create this wallet by yourself? Or did someone "help" you do this? Did you get a phone call, or email, telling you what to do?
I don't know if it matters but I did open an electrum wallet on my phone. It seems somewhat different than the PC version. I don't see the 1Nvh... number on there anywhere. I just recently opened this wallet when I discovered the problem I have. Haven't done anything with it except look at it. I don't think the two are connected in any way.
It sounds like it's unrelated.
Regardless, is it your expert opinion the bc showing on the blockchain under 1N8vh... is "locked" there having no way to be moved to my wallet or anywhere else for that matter?
Like all Bitcoins, it can only be moved by someone with access to the private key.
(Is this the kind of thing "miners" look for?)
No. Miners don't look for lost coins, but scammers prey on Newbies (and on experienced members too).
It's really not that much money to go further down this rabbit hole any deeper.
I'd say dig a bit deeper. Try to remember what exactly you did when you created the wallet. How did it get it's name ("1N8vh...")?
Yes, I created the wallet on my own. Did a search for how to buy bitcoin and then looked at several wallets. Chose Electrum because it was highly rated. When I opened the download the Electrum 4.3.4 line was at the top along with the 1N8vh... no help from anyone. (I should have done a bit more reading up, it appears.)
I am totally in the dark about private keys. I've seen where they're listed in the pull-down menu but have no idea what to do with them. It just says sweep or export. Is there some kind of connection between them and the 1N8v... label that might give me access to the coin?
