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 should be. It 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.
