I'm curious what will happen to Bitcoin after the next halvings, especially the last one.
There's a chance that miners will leave the network leaving Bitcoin crumble to dust and there's a chance that only the transaction fees will cover the fiat cost of mining plus some benefits.
The range is pretty wide and the truth is always in the middle.
OP is correct. Any amount is a possibility in 2035, from 0 to any big number we can imagine.
May be some miners leave mining but i think majority of them will stay with their device because by that time most of the miners will have got their ROI back and after deducting electricity cost what they will be earning is pure profit for them. With supply and demand principle also, price of bitcoin should be as high enough by that time so that small portion of bitcoin as fee could be enough for them to get some profit. However nothing is guarantee and even real satoshi may also came up to media by that time, who knows what will be situation after that.
There will always be miners that find profit. If some miners leave, then the difficulty goes down and the system self adjusts itself to provide profit for other people. There will always be a clear incentive for some people to keep mining. As the price goes up, the deflation progress will not be a problem.
