Where is the trust then ? Why would that very cartel do sth 'bad' ? Could that 'hide' ?
As a simple example. Then Bitmain/Jihan Wu and the mining cartel will have a better probability to, increase the block size/remove the limit, remove the Core developers, even if if the users/community do not want both.
Plus if no one ran full nodes, you want the users to trust the miners?
You just must trust HONEST miners - as described in the initial financial term sheet of Bitcoin - read the White Paper - that is binding, only.
But trust who? WHO ARE THE HONEST MINERS?
Bitcoin is robust because it was designed to assume that EVERYONE can become a BAD ACTOR against the network.
really everyone ?
Why long term investing miners ? Big enough to really do sth bad ?
Who's good to you, would not be good to me. Who's good for Core, would not be good for the big blockers. Who's good to Faketoshi Wright, would definitely good for Roger Ver.
Should we trust the miners to hard fork to Bitcoin Unlimited evsn though there's a technical debate that it's bad for the network? What would happen if the mining cartel was co-opted by the Chinese government? What would be the last line of defense to secure Bitcoin?
