How Stored :- Not Known
Source of transfer :- IRC
Bitcoin Address :- No
Wallet.dat file :- No
S/w used :- Bitcoin Core
How did you use Bitcoin Core if you don't have a wallet.dat file?
That makes no sense at all.
You can't receive Bitcoins if you don't give the sender a bitcoin address.
Pl Note :- I was asked to install a software which turned a normal hard drive to a nano ledger s.
It doesn't work like that.
The Ledger device uses a special USB hardware with a special firmware.
You can't just install the software on any USB.
I have used raspberry pi's (raspbian jessie) to see the coins
You can't see coins; Bitcoins don't exist at all.
They're just stored as UTXOs on the blockchain.
What you need to spend certain UTXOs assigned to you are private keys (they start with 5, K or L), if you don't have a private key then you don't have any bitcoins at all.
and validate its settings and it really does work
How exactly do you "validate the settings"?
What works?
but only thing is ,I am not able to take the bitcoins out of a text file.
WTF?
Bitcoins aren't stored on text files.
What exactly is on the text file?
Is it a string of alphanumeric characters starting with 5, K or L?
Post the first 3 or so characters.
Either you were scammed or you're trolling.
