Mining crypto is certainly easier then it was mining silver in medieval europe ;-). I took this shot down a spiral staircase into the depths of the Sala Silvergruva.
The Sala Silvergruva is a silver mine in Västmanland, Sweden. It was in continuous production from the 15th century until 1908 and provides a great deal of the riches that made the Swedish empire so powerful at the time.
