What would that do? It would cost about 72 billion dollars a year today to cut the tx rate to a tenth of current assuming other miners kept mining. Transactions will still confirm fees will be juicy. Ecash btw on the same mint would be untouched. Would probably explode. Harder for me to say what Lightning would do. And we’d probably see it coming from a mile away because nobody would be able to buy miners for a long time.
