I don't know, I just had a transaction for only 0.03 BTC that cost me 89000 sats in fees. The problem is I have a lot of small transactions in my wallet and even small transfers take lots of bytes! This is the kind of thing that could kill bitcoin!
And in some cases, even if you paid that much fees, your transaction will take more than half a day to be confirmed. I do not know how much more bitcoin users can take this. The more the miners delay the activation of any of the solution, the more damage it make to bitcoin
Yes, that seems to be their deliberate choice
Namely, try to postpone any solution for as long as possible since virtually any solution would make the fees they receive for confirming transactions to decline. That's why they are rogue. If I were them I would likely do essentially the same but since I'm not one of them I'm telling how rogue they are. But even if they succeed in their effort of putting grit in the machine, they are still shooting themselves in the foot over long term. Some day some coin which is not constrained by the mining monopoly will dethrone Bitcoin and then miners will have to walk home
