I eventually remembered that this address was when I was using Tails OS and the installed BTC client (in 2014) - I presume it is Electrum.
I managed to restore the account using the address (1HgLRgEHcwpnHErdkFnbGgHDtK72WNAEGH) which is visible in Electrum along with the available BTC,
however it's watching only. I have a list of words (17 in fact) and have also tried 12 as the seed when restoring the account but to no avail, I even tried an older version.
Is it that I used a different BTC wallet software?
The words I have are incorrect?
Just forgot what I am doing as I last used the address and software in 2014?
Lost the BTC, can see them, but no touch.
Any help is appreciated.
Thanks
There is no version of electrum that had 17 word seeds. You used some other wallet in 2014.
You need the private key for your address in order to be able to spend from it. In some wallets, like electrum, all private keys are derived from a single seed. So you need either the seed or the address specific private key. Since you have no clue what wallet you used I suggest figuring that out first. It's not electrum, though.
