I used to mine for bitcoin, just before it reached $1000, but when it fell dramatically it was pointless with the cost of electricity in the UK so I sold my rig.
Not sure about your wallet as I have been out of mining for a couple of years, but I'm sure there is help on google.
Good luck with your treasure hunt, and great to see you back on steemit.
I wish I had been more alert to the opportunity of mining back when Bitcoin was around $1000.
