Is there enough power throughout the rest of the world to keep bitcoin running and confirming?
Confirmations would slow down for a while (more than 10 minutes average between confirmations). Then when we reached the next difficulty adjustment period (every 2016 blocks), the difficulty would be reduced and everything would continue normally once again.
the problem is the time between these 2016 blocks... if big miners decide to stop at same time we would have a big delay until these 2016 blocks move.
I am not really sure about this but weren't the confirmations being made by miners? If everyone stops mining, how would we get our confirmations? I probably miss something because if it is true, when all the bitcoins get mined, there won't be anybody to confirm transactions anymore...
not exactly that but if EVERYONE stops the network would stop and that would mean no confirmations.
When all bitcoins get mined, miners will do it for transaction fee's.
