I think nano is about to rise from its ashes.

I wasn't referring to the block size but to the countermeasure mentioned in the medium article, that is

Ok yeah this might mitigate the problem.
Remember that in that environment the selfish behavior would be for every miner to modify its code to take advantage of this strategy. One would have to hope that most miners wouldn't do that for the good of the network overall but that's not selfish behavior.

I honestly couldn't understand what different it makes on the matter whether block size is limited or not. Regarding the countermeasure, a miner could just use a modified code for the node to get rid of it. It's a countermeasure only on the surface.

What I ultimately meant is that if the fork is for the good of bitcoin in the long run, it will inevitably be used. I'm talking about forks with the purpose of saving bitcoin (if it were to become necessary), not forks based on different views like bch.

Yeah I guess it's going to be gradual rather than sudden.

As is proved in the paper, an environment where fees are the only source of revenue for miners makes selfish behavior not align with the correct functioning of the network, unlike what happens in the present.
Yes, I meant a hard fork which could happen if enough miners want solve the detrimental problems that I've been talking about.

I've been thinking about the future of bitcoin in the decades to come. Like many of you I think that bitcoin will become the world's reserve currency, if it weren't for one little problem: miner reward. I know this problem has been discussed in the past, but I have not seen much discussion in the present. There is a great paper on the topic https://www.cs.princeton.edu/~arvindn/publications/mining_CCS.pdf, which shows how unstable the ecosystem becomes once block rewards are taken out of the equation. Fees will not replace rewards in the sense that incentives change. How do you think it will affect future development, and when do you think this will have the first concrete manifestations both in network dynamics and price?
Do you think it will fork in other versions where there is always a tail reward like in other cryptocurrencies? If that were to happen it would destroys bitcoin's case as having a finite supply.
These issues are far ahead and I'll probably be dead before they will actually become tangible issues, but I think it's important to discuss anyways.
I'd love to hear opinions from someone who's more knowledgeable than me, so thank you in advance for any reply.
