It seems the question is whether the trend from the current block reward to the minimum (subsidy) reward is too fast? What criteria would deem the trend too fast? Are miners running for the hills as we speak? I'm only trying to clarify what exactly the problem is.
Is the issue simply that XMR's emission schedule isn't similar enough to bitcoin's?
Preface: I operate at about 1/10 the speed of smooth with <1/10 of his knowledge and what follows was written before his post. It is another side I have seen discussed and I wasn't even thinking of the mining aspect. Since smooth believes the value must increase in order to keep miners then what follows should be taken with that in mind. Also realize that I am not in anyway qualified to speak on the subject especially considering the talent in Monero. OK so why is this idiot doing so? Selfishly to help me understand it. Also I don't presume I'm the only idiot here so maybe they can learn something from the perspective of one of their own.
I'll give my observations although I believe you know more than your question suggests.
It seems the non selfish argument is along the lines of a) people don't want to buy a coin that is mostly mined. If that is the case almost every coin will have this problem at some point. What does slowing emissions so it takes another year or two really accomplish? I guess a better distribution but that comes from adoption because it is useful.
therefore b) they believe the time it will take for adoption to occur will happen at a time when most coins are already mined. This is due in part to the time needed to develop Monero to the point where it can be used by the infrastructure that also needs to be built.
I have no idea if the central premise is correct. For the people that will find Monero useful, will they really care if it is mostly mined? I understand Risto's concerns about this but I wonder if this is because he is looking at it from an investment perspective more so than the perspective of a Monero economy.
I definitely have my reservations, but so far it seems we've mostly been thinking inside of a very small box. You make valid points that should be looked at from another perspective:
a) people don't want to buy a coin that is mostly mined.
Which people are we talking about about? Bitcointalk investors? Grandma? Assuming the answer is both, let's consider the latter as a long-term goal. Will grandma ever really understand or care about mining? Will she ever understand or care about block rewards and distribution? What will matter to grandma is how easy the money is to get, and how easy it is to spend. Of course there's the argument that you have to conquer this pond before entering the next, but I'll leave that alone for now.
If we really want to take the non-selfish approach, we have to consider the options that
can't make us rich.
If that is the case almost every coin will have this problem at some point. What does slowing emissions so it takes another year or two really accomplish? I guess a better distribution but that comes from adoption because it is useful.
I agree it will always be a problem if we're trying to create a widely adopted currency
that will also make us rich. For example, a perpetually increasing block reward would never punish new adopters regardless of their timing. It would only punish investors like us
But we will continue to paint ourselves into the same corner expecting a different result.
I honestly believe we have to let go of our ideas of how cryptocurrencies
should work if we ever want to win the money race.
And no, I'm not advocating any radical changes to XMR emission, so this reply is a little off topic.
