> Miners can game this system by moving their own coins in 100% fees transactions, just to produce more coins. You have one million BTC? No problem, just move them as fees, and you just created 100k BTC out of thin air, just because you are a wealthy miner.

Hmm, I believe you're right about that. If a miner can make 1 BTC of fees by honestly mining + 0.1 BTC of inflation, they could instead make 2 BTC by mining their own transactions with 20 BTC of fees. That does sound very gameable. I rescind my suggestion. 

One could imagine modifications to that suggestion that attempts to make it more difficult to game directly. For example, if an average sum of fees/block was calculated over a window (eg 2 weeks, 2 months, etc) and 10% of that was released in coinbase rewards, you would eliminate the possibility for individual miners to game the system. However, you would then have to consider the group of miners as a whole - since they all have an interest in increasing their revenues, it certainly seems like a dangerous incentive that could lead to runaway inflation. So perhaps even extensions of my suggestion are too gameable to be safe.

But my point still stands that tail emission is not a permanent solution. One permanent solution would be some constant inflation rate (eg 0.1%/year). Given that the necessary security is a function of the total value of the currency, perhaps that would be a reasonable natural way to scale security as needed. 

Again tho, I haven't seen any convincing evidence that any solution like this will likely be necessary at all. Total collected fees will also scale up as bitcoin grows, probably quadratically (since the value of the network grows quadratically). I'm rather more inclined to think collected fees will get far *too* high - ie substantially higher than needed to pay for sufficient blockchain security.

Hi Peter, everyone
This issue has been discussed thoroughly in bitcointalk, general discussions are more suited to forums, I believe, still ....

First and foremost, it is more than obvious that bitcoin block subsidy algorithm is a total disaster, not just for the zero subsidy security consequences, but also for the overly rewarding scheme that favors (few) first-runners against (masses of) people who join later, a policy that looks to be a cheap marketing trick rather than a decent strategic monetary, system design, no matter how natural it is presumed nowadays, after being implemented by Bitcoin.

For now, the brilliance of the idea behind Bitcoin and the enthusiasm have compensated for its bizzar, upside-down inflation policy, in practice as newcomers have been paying the price to lucky first-runners and adopting anyway.
Is it happening for low block subsidy? Is it going to be solved somehow? I don't think so.

With subsidy still being the major (like 90%) portion of the block reward, there is an equalizer factor pushing equilibrium by paying security costs on behalf of current coin owners.Note that every single new bitcoin paid as subsidy is actually paid by the rest of the wallets proportional to their balance.
Other than its direct contribution to security, once understood as a ballance-based taxing scheme, it is a crucial mechanism for re-distribution of wealth because to compensate for their costs, unlike speculators (who are among the worst adopters of Bitcoin, and unfortunately the most influencers), miners are used to dumping their coins, providing more fair opportunities for people to join.
So, halving and the hard cap, put both adoption and security as risk, It is why, unlike  "believers", I'm deeply concerned about a future with low block subsidy because it puts both security and adoption in an awkward situation.

Additionally, It is not considered an engineering practice by any measure to speculate about the security of a system that we abundantly recommend to friends, family for joining.
We need proofs, security proof, ease of adaptation proof, etc.,
Fantasies are not proofs, having faith in a magical incentive mechanism that fixes everything is not an argument, let alone being a proof.
Incentives are irrelevant, rules, schemes, projects, and so fort, matter. There are always incentives in games, but rules are in charge of determining the fate.
Without rules, there is no game, flawed schemes and rules move the game behind its equilibrium to fail eventually.

I've not to mention the unfeasibility of tempering Bitcoin's basic consensus rules, Bitcoin rules are not subject to change specially when it comes to something that is widely considered a basic characteristic, a Schelling point, and so forth.
 
So, it is the paradoxical situation: we are exposed to, on one hand, it is a deficiency and on the other hand it is inevitable because is critically hard-code to Bitcoin, advertised more than any feature as its identity.
But it is our job, isn't it? Dealing with the impossible and taking care of it, but I think before reaching to that point we have to settle the basics.:

  1. There is a problem with long term security and adoption consequences.
  2. It is built deeply to bitcoin consensus rules, and considered a critical
  3. It is not going to disappear magically, neither it will be addressed by whales, etc.
  4. The 21M cap, halving, and generally, Bitcoin consensus, is not subject to change.

Don't panic, it is not exactly a catch-22 situation. Tip:
It is always possible to help a system without aggressive intervention, either by smart tweaks or by supporting it using other system(s).

Cheers, Ali Ashraf

Hi Jaroslaw,


In the Prisoner's Dilemma the prisoners cannot communicate. In Bitcoin large holders are able to communicate with each other. Also, prisoners need not make an all or nothing decision in Bitcoin. Miners can join and leave the network freely over time. You can change your decision based on the decision of others.


The Bitcoin design is such that security is volatile but the issuance of blocks is timely and evened out to a 10 minutes average even after the reward is exhausted.


The existing incentive that miners earn money for including transactions is enough to motivate human nature. Transaction initiators have an incentive to mine and run full nodes for personal interest.


>Noone will waste his renewable energy on unprofitable Antminer while he/she can sell this energy for the market price.


The law in most jurisdictions prevents the resale of spare electricity unless an expensive license is obtained (and in most cases no license is available as the government maintains a monopoly). Mining with waste electricity is reducing losses. Another incentive to motivate human nature.


Bitcoin holders can be enfranchised into any new system. So, no need for bike shedding the original design which is a Schelling Point.
