There are more than 230 countries in the world, and I don't think that mining can be banned in all of these nations at the same time. Even if all the countries ban Bitcoin mining, there are dozens of other options. We can shift mining rigs to ships anchored in international waters and connect to the internet using satellite phones or Dish antennas.
230 countries.
But you will have to cut off the list those that don't have enough energy or the energy is so costly it does not make sense to mine.
And mining in international waters, aside from being taken as a funny joke it's impractical.
You would need massive amounts of fuel, generators, and above all protection.
The cost would be so high it would not make sense to build a farm on the open seas.
The only way a complete international ban might be avoided would be by totally decentralized miners doing hobby mining with 1-2 miners at home, after all , the chain can run with a single miner.
But in this case, a 51% attacks has an almost guarantee chance of success.
how they know this place mining or not.
bitcoin fee will be big and network slowly.also may end bitcoin
Bitcoin fees and speed of tx are not affected by the number of miners.
How would they know?
Simple, checking who does more than 900kwh a month.
Since:
http://shrinkthatfootprint.com/average-household-electricity-consumptionIn the US typical household power consumption is about 11,700 kWh each year, in France it is 6,400 kWh, in the UK it is 4,600 kWh and in China around 1,300 kWh. The global average electricity consumption for households with electricity was roughly 3,500 kWh in 2010.
There is no country besides the US and Canada where the average household consumes even 2/3 of what an s9 does.
So it's like cherry picking.
