So how can they systematically stop work and create network congestion? However, all miners know how they will benefit. The most important thing is that the miners will mine independently if anyone wants to slow down they will lose. His reward will be less than others. If 90 percent of people stop mining, 10 percent won't stop doing it. In this their profit will be more. No one will want to harm them. They will try to perform their tasks quickly and bring the rewards to their account.
He also said that as long as we don't need the permission or license of a big country such as the United States, Britain or Russia to do mining, the miners will continue the mining activities without disturbing their mining but with the highest importance for profit.
there is more then one pool
if 90% of one pool stopped. then that pool will make >90% less blocks and >90% less rewards
other pools then make more frequent blocks due to less competition. so their block count and rewards go up
however the 10% that want to continue will be left on a dying pool which make >90% less blocks so their rewards are less. if any. yep if you have a small pool your chance/luck decreases exponentially too. its not a fair %
this will mean that the first pool only gets rare blocks or dies
however 10% moving to another pool means a boost in blocks for that other pool but now they have to share with an extra 10%
..
also governments dont need to ban mining they just need to make power companies apply a premium electric tarrif, and then the governments then tax it at 30% ontop and just price people out of wanting to mine in certain countries
