What's harder--Sowing seeds of discontent or mining Bitcoin? I'm leaning towards the former, because the sowing has to take place hourly, if not minutely, whereas you only have to set up a mining rig once (the analogy works provided you don't upgrade).
Woe is upon us if anyone figures out how to convert one of those AI online chat bots into a forum trolling rig, and sets it "mining" on here!
