I didn't miss anything.
Your point (which was incorrect) was that miners would lose
FIAT revenue even if the transaction fees went up a HUGE amount. To make this false point, you pretended a huge crash in fiat exchange rate (that may or may not happen), a huge increase in fees per transaction (that may or may not happen) and even given those attempts you STILL failed to demonstrate an actual loss for the remaining miners.
My point was that any increase at all in fees (regardless of whether it was $0.01 or $99.20) would result in an INCREASE in
BTC revenue for the miners that don't shut off their equipment, and that even your extreme examples still result in fiat profit. In reality, it is possible that the remaining miners might encounter a temporary loss of FIAT value. It's difficult (impossible?) to know ahead of time exactly what the exchange rate will be, or what the average transaction fee will be, or what the transaction backlog will be. However, they will certainly encounter in INCREASE in BTC.
If 60% (or 70%, or 80%, or whatever arbitrary number you feel like you want to pick) of the hash power were to suddenly shut off, it would reduce the total number of blocks per day that the USERS see solved, but it would have no effect at all on how many blocks per day the remaining miners are paid for. The
block subsidy revenue (in BTC) for the remaining miners would be completely unchanged. The
total revenue (in BTC) for the remaining miners would go up (or down) with any change in transaction fees per block. Whether this change in total revenue (in FIAT) is positive or negative depends on how much the transaction fees per block change and how much the FIAT exchange rate changes.
Then, once the normal difficulty adjustments return the system to 2,016 blocks per fortnight, block subsidy revenue (in BTC) for the remaining miners would increase significantly, and the transaction fees would return to equilibrium.
Let's stop feeding the troll...
This is an excellent idea. I think I'm done watching this thread. I'll remove it from my watchlist.
