Heavy fines for anyone caught using a cryptocurrency, that should sort it. As far as I can tell, this currency based on nothing tangible and only serves to benefit a few while causing misery for millions. It causes massive scarcity in computer equipment, uses up valuable resources when we are supposed to be conserving energy and seems to be the main currency for criminal activities such as drug deals. Is everyone making millions from this mining stuff? It seems everyone is taking a **** on gold toilets and wiping their arse on fifty pound notes just for leaving their PCs on 24/7. I feel like an idiot for just wanting to use my graphics card for gaming. Like I am Fry in that episode of Futurama when all he wants to do is eat the can of anchovies. Remember when people left their PCs on 24/7 for medical research, or helping find ET. Those seemed like simpler times and a nicer society.
