I have been mining WTC / WTCT for the last week. Its a very unique coin to mine. You essentially solo mine. I am averaging one block a day. The cards I am throwing at it are 6x 1080 ti.
Quick math that comes to $5 per day per 1080 ti.
The cards run very cool and quiet. I dont have numbers but power usage has to be very very low.
To my knowledge this is a Windows only mineable coin at this time. Requires a beefy CPU as well.
I only have celeron CPU for the mining rig, so is that a no go?
