Won`t the people with the most miners at that time stay on top forever?
They will be the only people to generate the supply or obtain supply from network fees when there is none left in nature.
Mining is a business. Whether miners succeed or fail depends on how well they run their business. Simply being the people that maintain the block chain won't automatically put them "on top forever".
Won`t the people with the most miners collect most of the network fees since they have the highest hash rate and push out all the small miners because the smaller miners will actually mine at a loss and go out of business running there machines at a electric power loss? At some point in time they will have to turn off their machines.
It is like my small family farm, I cannot compete with the bigger corporation farms, they have 1000`s of acres and can sell peaches at a much lower price than me, pushing my small family farm out of the game. My cost of operations exceeds my profit intake, especially with the min wage going up. I just can`t afford workers.
Not all small miners mine at a loss. It depends on costs. As long as it costs you less then 1 BTC to mine 1 BTC, you will make a profit, regardless of your hash rate. Now, like your farm, big miners can lower costs more effectively than small miners, so it is true that small miners will have a more difficult time making a profit.
So, Won`t 1 miner win in the end, the biggest miner will just keep getting bigger, and everyone else will be left in the dust?
Don`t you think that miner will be a central banker, for they had the most fiat before hand to buy the most miners?
So a central banker still wins.
There isn't 1 farmer in the end, and similarly it is not likely that there will be 1 miner in the end. And while central banks and governments print all the fiat, that doesn't mean they will become miners.
