It's not that strange, 2013 was the oldest wallet/ backup I could find at the time and just assumed that's how far back I went.

Since '21 I have found access to older emails and reference to the payouts to this wallet from a now defunct mining pool.

I first remember mining BTC on a single-core i7 CPU, so I was about even earlier than that too.

And no, this was a different wallet that I managed to crack the encryption on and was in fact an empty wallet from 2013 incorrectly named.
