Re: The cost in kW
The numbers are:
The entire electricity consumption of Ireland, for the equivalent of everyone in Ireland making two transactions per month. People in Ireland typically make 17 transactions per month, so if they switched to Bitcoin, they would have to increase electricity production to about ten times the current level.
If one person paid for a TfL bus fare by Bitcoin, the transaction would use enough electricity to take that bus to Leeds.
If everyone on a Northern Line train paid for their fare by Bitcoin, all their transactions would use enough electricity to take that train to Napoli in Italy,
