Eventually, all the revenue for the miners will come from transaction fees. Before then, the amount in fees will need to be about the same as the subsidy of new bitcoin being mined. That might happen for the first time very soon. 🤩

It doesn’t have to be one way or another. The market will market, in regards to security supplied to the network.
So, we don’t have to push the miner’s fee higher for any reason, just make transactions when we need to. We have ideas of what the market will look like, in a couple halvenings, but we don’t.
