Hi i have a question, i hope someone could answer it
As of now, the circulating supply of Bitcoin is 16.6M
I was wondering what would happen if it reaches 21M?

Will bitcoin still work even without mining?
Or will bitcoin fall apart?

In theory, the price should be so high that it is economically viable to mine the transactions profit being only the fees of them without any newly generated coins as rewards.

Some theorize that this will not hold and suggest a small % of inflation. I think it's bullshit, we don't need inflation. If someone doesn't want to keep mining and reap the profits of fees, someone else will. The system will continue self adjusting just like it does now.

Inflation would never have enough consensus for a hardfork.

I had the same idea. Who will confirm the transactions without mining fees? and what will be bitcoin price then?

Bitcoin would still work.

Miners would get paid differently, because there would be no more block rewards. They'd get paid only by fees. Fees may increase as a result, but in theory the value of Bitcoin should increase as well so the % of a transaction devoted to a fee may not have as much change.

If supply is stagnant there will be a greater effect on value given the same amount of demand. This is when the value of bitcoin could really take off. Unfortunately all bitcoin won't be mined until the year 2140. BUT, given the process of halving block rewards (and therefore the creation of Bitcoin) we'll have mined nearly all of bitcoin well before (like many many decades before) the last satoshi is unlocked.

Don't worry mining fees will exist every time. Just remember a few months ago, when BCH and BTC were 'fighting' and miners were hopping from and to the different chains to mine. This caused high fees on the BTC chain, so the miners earned the block reward and serious profit from fees as well. This amount of profit from the fees should be enough for the miners if the block reward disappears.

Well if that's the case. the concept of bitcoin of being decentralize and low transfer fee will be gone...
i think a new coin will rise and replace bitcoin 50 years before it happens..

that's one of the questions that almost all bitcoin users use when bitcoin gets mined, I think bitcoin will still work even it will be something rare and increasingly expensive like antiques, such as economic theory the more difficult things can be done then the more expensive it is one of the trade laws.

http://lmgtfy.com/?q=what+happens+when+all+the+bitcoins+are+mined

After bitcoins are all mined (reaches it max supply), miners will not get reward from generating new coins, but they will get transaction fees. It will take a while for bitcoins to reach its max supply. By that time, bitcoins will be worth more and the transaction fees may be more than enough to keep miners motivated to secure the network.

bitcoin halving it is..
i think when the supply is out the demand will begin to shoots up high because there is no bitcoin to be found you'll only gain it when you buy it or someone had paid you bitcoins.. it will become a need so everyone will need it this will cause its price to continuously grow its value..

I think when all of Bitcoin are in curculation it is possible that transaction fees will rise because of increase in the demand for transactions.
Without mining Bitcoin transactions won't work but mining all the Bitcoin supply doesn't mean bitcoin miners will stop mining, miners still can make profit from transaction fees but the issue is, is transaction fees enough for miners to make profit from it? But It is too early to think about it, some experts said that all Bitcoins will be mined in 2140.

Hi, your question is searchable and it's has been answered many times. The summary of answer is this:
1. Miners will still work and will still have a profit or reward and that is the transaction fees. In which i think is still profitable.
2. Bitcoin will not fall apart, it will continue to grow on transactions and volume.

Well no one would know of course we are hoping that it will be worth hundred of thousands or  millions but it is possible that bitcoin could be worthless. Also there are other coins that miners can mine.

It is still years and years before every bitcoin is mine so as long as we are on a bull ride, i will ride it.

bitcoin will circulate when all supply are mined and the demand will also be high and the value will be high too. the fee will also increase to pay miner for confirming transaction but it will take years to mine all the supply.

if bitcoin is still used, maybe the bitcoin price will be to the moon. but if not, maybe slowly, bitcoin price will reach its lowest point. well, it could be the price of bitcoin to be completely stable.

Then the bitcoin supply will run out, BitCoin can only deflate, ie increase the value
The marvelous bitcooin that currencies do not have is the quantitative limit

I did not think about it, that time was in 2140 when BitCoin could have gone into the museum and was in the history books.

bitcoin has reached the cap and it cannot be mine anymore year a go already and as bitcoin now has limited supply but continue on demand nad be known more in the worll. it will surely hit the moon ! and this is good for bitcoin holders !

HAHA, many people also think that bitcoin will go to the moon when the supply reaches its maximum.
Only 21 million bitcoins have been created, but the world has 7 billion

And I think BitCoin will fall, because the weaknesses, limitations and disadvantages of BitCoin is much more than other currencies.

If bitcoin reaches its maxed supply wouldn't that create a situation of more demand less supply and the prices could go high maybe. Miners will also get paid differently as the only thing they would earn from is the payment fees. So maybe when the supply reaches max supply bitcoin prices can go high.

The demnad will be very high leading to a higher price

Haha, your opinion is interesting and funny
I also thought then that the value of bitcoin would be worthless
Wait and see
By the year 2140

The bitcoin value will become more expensive if will reach the maximum supply or the price will stock up at the highest point and it will not going down anymore. Miners will be affected because there is no more blocks rewards and the transaction jobs will become expensive but will be few so many of the miners will not going to be needed anymore so that the fees will not become cheap therefore some of them will probably shift to other coins like ethereum in order to continue the profit.

I think bitcoin will still work but no more mining so it is very difficult to find and become rare and the price is definitely very high

That's what we call scarcity, and that's one attribute of all money and where there is scarcity of any legal tender there's a corresponding demand of it and hence an appreciation of it's value; the same can be thought of bitcoin should we max out all that's supposed to be mined.

At first, that was really one of my concerns. But then one day my brother and I had a small talk about btc and this concern came up. So yeah, basically we have the same opinion like others here that mining will still continue as there will always be a fee to be paid on every single transaction and that might increase too as there'll be no more btc to mine. And for sure there will be more upgrades to cope with the situation. Btc will never fall apart and its price will then be unimaginably expensive. But then at the end of the conversation my brother and I came up with an agreement not to think of it anymore. Simply because by that time btc have been mined we will no longer be here. Well not unless we made it to our 170th birthday.  ;D

And how many of the 7 billion population would be using Bitcoin? Maybe like 1% tops or even lesser. The point here is looking at the long term future when every single coin is mined and yes, expect it to reach the moon by all means.
It would take many decades to reach the max supply as the block reward would be decreasing and difficulty would he increasing exponentially.

ithink reaching 21m is didn't happen because we are have 2 hardfork for now itmeans half bitcoin was seperated so that bitcoin is going down after the hardfork.

Why would a new coin need to arise if Bitcoin is working as planned 100 years ago?



Bitcoin wouldn't deflate in value, it would inflate in value! When demand exceeds supply value inflates!

You're confusing the inflation of value of currency with the inflation of prices for goods and services (which is the deflation of the value of currency).

So its very imposible that all people can have bitcoin, if people reach the maximum in that case i think bitcoin price will have more value. So many people can use it for every day. But im sure not all people can have bitcoin.  That's why there is a lot of kind of any coin. (Correct me if im wrong)

Don't actually know what happens next after the max supply is mined. Google returned this-
After 21 million bitcoins have been mined, no more can be generated, but the network will still need to be secured. The incentive for mining might diminish, but the generation of new blocks is important to provide the publicly available, network-distributed ledger of transactions. Miners will still be able to turn a profit from transaction fees.

When Bitcoin reaches its max supply its value may surge up because it will be limited. One thing I know in this world is that if something is rare it will be of high value. Gold and Silver for example. This elements are both expensive but gold has a higher value than silver because it is more difficult to find. Diamond has a much higher value than gold and silver because it is harder to find than both gold and silver and It is harder to produce. I am pretty sure bitcoin will be react the same. Of course there is still the possibility that some forces will act to bring down bitcoin.

Quite the opposite.
It would create that situation.


Scarcity does not always guarantee high prices.
The price ratio for silver does not reflect the available supply in the earth crust.
Also there are 5 other rare metals, some of them 10 times more rare than gold but they aren't more 10 times more valuable thna gold.
An example will also be titanium which if far more expensive than zinc.


Nothing is going down, stop spreading FUD.

Also, about the 2140 date.
That is not the date when the last bitcoin will be mined. More like the last few satoshi.

https://media.licdn.com/mpr/mpr/shrinknp_800_800/AAEAAQAAAAAAAAOIAAAAJDcwMDQwYjViLTdjZjAtNDBiZi04ODhjLTZlZDdjMDUxNDk1Mw.png

By 2040 miners will receive 0.09BTC reward by block and by 2100 around 600 satoshi.

It's not the appropriate question here to answer it i think the confirmation of transaction fees could not be done without the mining fees and just imagine what would be the bitcoin price at that time. I cannot justify here how could it be possible but yes i know one thing that mining fees will exists at every time. If the supply is showing no activity with the same amount of demand in action then the value will rise for sure. This imbalances in the demand & supply will make the price of the bitcoin fall, lets see how this prediction works and how the bitcoin moves in the future.

Woah thank you for this Picture... I started trading bitcoin since 2013 and i heard of the news about halving. But sadly i didn't believed it and i was convinced that bitcoin was dying when mtgox was hacked... but now i know that bitcoin will live on and grow big time :D

When bitcoin reaches its max supply no more coins will me mined anymore. The miners will simply mine the transactions from then on and no more blocks. Now there is no reach to think that the supply will be small for the world population because satoshi has thought of that previously and that is why the limited supply makes it only a more precious asset - hence the price will increase in future and there is no one to stop that. Every person will be abble to theoretically buy bitcoin but the price spikes will happen.

How can you say this??. bitcoin is the pioneer, limitations and disadvantages will always exists on other currencies but you cannot just conclude that because of the limitations and disadvantages a coin will fall or die. The support from the community is one of the biggest requirement of a coin to continually live and as of now, the support from the community to Bitcoin is incomparable to other cryptocurrencies.

After bitcoins are all mined (reaches it max supply), miners will not get reward from generating new coins, but they will get transaction fees. Bitcoin will not fall apart, it will continue to grow on transactions and volume. ;D ;D

I think if bitcoin reach to his max supply all the bitcoin miners will join intry only and earn bitcoin in transaction that makes by people who are using bitcoin transaction

in my opinion bitcoin will not be added if the supply is still widely circulated, if the supply is multiplied then the bitcoin price will go down, therefore bitcoin now given the limit let the price do not drop drastically.

It's either going to skyrocket because of bitcoi'sn scarcity, or it's going to tank because of the missing miners, a big driving force on the btc price.

i think bitcoin will collapse because the Fee for transferring will be so high

Based on my research in 2015 the total supply of bitcoin is 6-5 million? I dont think so but i know that if bitcoin got max supply i know that bitcoin is get increase to the highest price becuase if the supply is limited we expect the price is high.

Nothing out of place will happen except that the price of Bitcoin will skyrocket. By the way, the 21m is the expected total mined coins but there is no way that 21m will be in supply even after everything has been mined. Of course there are going to be lost coins in transaction or lost private keys to trace some coins.

Let's just relate this in the law of supply and demand. When the market price rises the supply of good rises and as it fall the supply falls. However, the demand rises when the price falls and it falls when the price rises. So, when bitcoin reaches the maximum supply meaning the supply falls and the market price is low and the demand is high. In that event many will demand to buy bitcoin. I think its just the norm because if they demand more then they have nothing to do but wait for its availability. Anyway, many had already using it. They must increase the supply. There could be a maximum supply but it should always be more than the demand.

It will not cost the coin to fall apart but most probably expect higher transaction fees since the miners will just earn from the transactions.

But when that time comes which is 20 years from now imagine how many transactions will occur at a single time. the current rate might be enough to compensate the lost of mining because of the increase in the transactions.

Once the maximum supply is reached automatically the demand will be high leading to price increase. Along with the same the transaction fee will surely reach big as there won't be any more mining further takes place. The mined coins that're into circulation in different forms generate the growth.

If bitcoin will reach its maximum supply and it cannot sustain the increasing demand the best way to settle this issue is to increase the value of bitcoin we should not be worry because bitcoin will stii circulate in the market as long as the owners are active and the demand continue to grow. I am also sure that developers are anticipating this thing that's why as early as now they formulate solutions in limited supply of bitcoin.

If one day, the price of bitcoin should be a very exaggerated price figure. I'm looking forward to it, but it will take me decades to get there.

That is why it needs more value so that miners will still keep on working on it.
If the price of bitcoin is soaring high then every miners fee will be valuable too.
They can still pay for their bills and somehow they will still have some profit.
But this will occur for a long time and we might not be seeing it.

I think you already have the idea but the way you have stated it made me confuse.
It should be put this way, at least in my own understanding of the said law. Since the maximum supply is considered to have been reached, it can then be considered a constant supply.
At a constant supply, the price rises when the demand also rises and the price falls when the demand falls. In case of bitcoin, I can generally say that more and more people are getting into this idea each day thereby making a constant increase in demand. So, to sum it up, when the max supply has reached, the price will continuously increase and people should consider it by now.

Mining won’t stop after total supply is in circulation. Mining is still required to confirm your transaction within different blocks in the same way as it is done today. So it’s not like mining just required to mine the coin but it’s more than that. It is also speculated that fees will increase in this period because miners will get their rewards or earnings from that way as they won’t be having reward from the pool directly. That could happen on prominent scale.

The price will be high which is economic to do mining and profit made from the transaction fees and there won't be any newly created coins.Some studies say that it will not hold small percent of inflation but i feel that the system itself will continue to generate as it is doing now or may be there is chance for new coins to show up or new btc will be created the once doing mining will get their payment in different ways a there wont be anymore blockchain rewards.They can get paid only by their fees so i think there is chance for fees to increase and transaction charges will go high and the value  of btc aswell.I don't think such situation will show up in the near future.There is a common law for everything when the demand increase it is normal for the price to shoot up and hence the once holding too many coins will be willing to sell off to get profit and hence supply of coins can be solved.

I read an article where there are things that happen when the bitcoins reach the max supply. It is said that Supply remaining in bitcoins is estimated at 21,000,000 BTC and when it is all mined. Bitcoins will be gone but I'm sure that the people involved in bitcoins will not allow it,

My guess is, the transaction fees will rise, even if it could have been low. Considering the same amount of bitcoin in circulation, a nominal fee would be good. It will encourage more transactions and more fee. Rather if they get greedy and hike the fee, their income will be the same, but as time goes the number of people using it may go down. In any industry the number of users is very important and keeping them in is very much essential.

Bitcoin will surely still work when it reaches its max. It would then bring about a circular chain of movement as a result of the fact that there would be no more production of it. The value might increase as well as fee charges(base on assumption).

Simple: nothing. The only thing that can happen is a grow on the price
I think that when all supply is reached, the price can reach like $20-30k
So need to wait and hold bitcoin :D

Many Individuals are thinking that Bitcoin will get to the top,if the  bitcoin are not been mined,but that is not correct because as it stand 21million bitcoins have been created, but only 7 billion  bitcoin are own worldwide,so what will make the difference if bicoin arenot mined

It will produce an effect opposite of inflation called deflation. Demand can grow while supply can't, making its value larger and larger. We'll probably be dead by that time tho.

maybe if bitcoin has reached the maximum, bitcoin will be stable in addition the bitcoin price will decrease as the number is growing as expected this time. of course this will take a long time to reach the maximum number (21M token)

Miners should be paid on a different stake basis. And I think by the time btc reaches the max limit. It will circulate around the market as a normal commodity since it has been fully used in all business transactions.

Mining will continue and the reward of finding blocks will be the transaction fees, as limited supply price should always increase so finding blocks for TX fees will be profitable and interesting for miners.

Yeah they say last coin will be mined in year 2141 which is far far away from current scenario. The year is calculated based on network difficulty and the total miners in place plus total number of hashing rate they are producing. It could happen that new miners with more advance tech might just come in the near future and that could increase the speed of mining and the period may reduce to unexpected number. So miners need not to worry until we advance off the chart.

People have different views about already mined bitcoin but no one is clear about real situation. I think when bitcoin come closer to end mining then the developers will plan for next of its new project that bitcoin might not end but I don’t think so that all the bitcoin will mine soon.

Most probably that developer enhanced the quantity of bitcoin in the system and by that time may be maximum would have been introduced bitcoin in their countries.

At some point in the future, probably around 2140, the last bitcoin will be mined. Once 21 million bitcoins are created, no more bitcoins will ever be created. That doesn't mean that the bitcoin world will come crashing down, however. Besides awards for hashing, bitcoin also provides transaction fees. Currently, these fees amount to only a tiny amount, only a fraction of a sent. However, as bitcoin awards go down, the fees will likely increase, as will the value of bitcoin.

Maybe the bitcoins increase its value so many people are interested in bitcoin but it's too late. But the good news with former bitcoin users because they can be more rich, if they accumulate bitcoin before it mined all.

After it reaches it max supply It will most probably be worthless. As it cannot accept micro-transactions anymore and this will cause many people lose interest in it. I see the price going down and the chain turning off.

I assume you are trolling. If not, then I suggest you read more and post less.

If the btc reaches to its peak definitely btc miners will gradually gone and find another resources though they can still get service fees if they still continue.
But if the case happened the price of the btc could be high because there no more coins added to its inventory.
The demand will surpass the supply.

it took a long time to reach 21M. but if bitcoin has reached 21M i think bitcoin will continue to work. and the effect, bitcoin prices will be very expensive because something rare will be very valuable.

Nobody has different views on this thing.
Just dumb people, lazy ones that can't bother to user search for a second.
There are 16793825 coins mined as we speak.

And it's clear as it can be that you have no clue about the bitcoin supply and it's cap.
NOBODY is planning to "enhance" the quantity of bitcoins available. This is not Fiat!!!!!


And why the doubt?


What has the max supply to do with micro transactions?
There is absolutely no correlation between the two of them.

And how do you think the chain will turn off? Do you even have a clue what the blockchain is?

All we have to do is convince other people to join bitcoin, because when all the people uses bitcoin,  the bitcoin will rise and rise even if it reaches the 21m, and we don't have to worry about it anymore.

If bitcoin reaches to its maximum supply then i don't think bitcoin will work Strongly Because at that point the supply will exceed the demand and thus the value fill fall.

I don't know where are you coming but I think you have a different view on this. Reaching maximum supply means all bitcoins are already circulated. Note that it will not happen in an instant so by that time, bitcoin is already distributed to a more number of users. Reaching the maximum supply could mean we now have a very limited supply of 21M bitcoins but the number of users are growing each day. I don't think the supply will exceed that much to its demand by that time.

After number of bitcoins will reach a mark of 21b, I suppose that it would be new blockchain organized, some kind of fork, clone. And all users who have bitcoins will get additional amount of new coins.  ;D

So it will be. In general it is difficult to imagine how Bitcoin will develop and be extracted further. If now the network is working so hard.

I don't think anything bad will happen to Bitcoin once it mines all 21mil of it. Miners will still get their pay via transaction fees.

I guess the miners will have a problem regarding the confirming transaction in my theory if that happens then it will be the start of another increase in the miner's fee because it will be an additional workload for them it is only right that they can increase but let us hope that if ever that happens that increase would be not that much.

I think the ammount of transactions would increase and after that people who mine would get paid enough confirming transactions. And second of all the price in my opinon would become stable, maybe that's not possible but in some theory it can happen from higher ammount of people who invested

The value of Bitcoin will likely continue to keep rising once mining stops. Fees will also be very high so miners will receive these fees for running the blockchain.

The World War 3! Every country will fight for it, water wouldn't be a matter, oil sources gonna burn, fliying cars, life on mars etc...

Of course just value of bitcoin will rise. I don't think anything else will happen.

maybe i don't know the answer but i know the miners of bitcoin will be pay. and bitcoin will be still work because bitcoin is like continue machine in internet. and mining fees always exist every time.

The value of BTC will be so high that we cannot reach the maximum supply. I think at a certain point, people will did it difficult to purchase BTC due to its astronomical value.

You are very interesting I really think bitcoin will appear in history books.

Then the price of bitcoin would be so high already.

When that happens, all Bitcoins will be in circulation (held by someone). At this point we will still need miners to perform transactions so they will probably be paid entirely by transaction fees. Bitcoins will become more scarce and therefore the price should keep increasing. This process will take until the end of the century, but Bitcoins can still be used after they are all mined.

Whenever the max supply would be reached , bitcoin's values will certainly skyrocket since it'll be considered as a rare item to get (such as for gold now if we apply the analogy gold-bitcoin ) . Yet people always think that reaching the max supply will be in no time , well people , reaching the max supply could take a 100 years more due to the exponentially increasing difficulty of hashing .

Miners will keep mining for transaction fees and not to create new coins , fluctuations won't be of a weight as they are now and the market will be unreachable by new comers which will make bitcoin traders impose whatever prices they want .

But i don't think that any of us will live long enough to actually experience all of this  :P ..

How the hell will that be possible?
The number of coins will stay the same, that's it.
How do you think supply will exceed demand when right now with over 3/4 of coins mined price is up 15x times in a year?


Go back to the wiki page and read before shit posting.
The price has nothing to do with the block reward.


God help me!!! Where do you people come from?
Why would mining stop?


And the flood of shitposters continues...
What is this additional workload you talk about it? Obviously there is none but I wonder what was going though your brain when you posted this.

Once the number of bitcoin reaches the maximum supply, I think the bitcoin value would grow higher because the bitcoin hodlers would be holding more and more. And as you know, the bitcoin price is driven by the market demand and supply. The bitcoin scarcity will start due to high bitcoin demand by the people. Therefore, the demand of bitcoin will be higher than the supply more than ever and that would catapult the bitcoin price to go beyond the moon, perhaps, to the last planet which is Pluto.  

After the Bitcoin reached it's maximum supply, i guess the price will be much higher because the total supply will just circulate, if the big players hoard their possesion then the supply will be lesser while the demand will be higher. Then there will be a price acceleration.

My bet is that Bitcoin will become irrelevant far before that moment, as new currencies rise in adoption and importance and solve more problems than Bitcoin and they do it in a better way. Proof Of Work, as it is now done for Bitcoin, is unsustainable.

Just follow the rules of supply and demand, more demand and fix supply what do you think will happen? Price increase yes.
Other than that, miners will be paid solely by users fee, So acording to my guess, transaction fee will be even higher, damn!
I need to accumulate as many as bitcoins before that happens

In my opinion miners still have to work to transfer from this block to another block in blockchain, that means their work never stop until they quit :)

It's not worth again for mining, even the transaction fee will rise. If the transaction fee is increased to the max people will quit from bitcoin and change to altcoin like bitcoin cash or something, and the miner will quit from bitcoin mining because miner will get ROI longer than usually and the bitcoin price will crash until maybe $100 or $50. In other words it is bitcoin doomsday.

If bitcoin reach its max supply expect the value of bitcoin will more likely will pump because of high demand now of bitcoin on cryptocurrency market.

read an article that if it happen the bitcoin will still work and circulate..
The miners will get paid in every transaction will made about coins . Just like what they do when mining
And some said that the supply wi be here until 2140
The difficulty will be more hard if were getting close to the supply limit.
Some said that the price will go up for those rare type of coins.. but who knows maybe this will not gonna happen

This, perhaps, is one of the questions that interests many users of bitcoins. There is no unambiguous answer to it yet. If this happens more than a hundred years, then there is no need to try to give an answer to it, because by that time bitcoin, if it still exists, will be completely different. Perhaps by that time, its number will also change.

It is almost impossible to speculate what is going to happen in the future, after more than 100 years. Bitcoin could disappear or lose its value in the next 10 years and thats why I dont think we have to worry about this right now because all of the actual users on this planet are going to be dead when the circulating supply will reach 21M. So it is absolutely useless to spend our time and energy to find out what is going to happen in the future when we are going to be dead. One thing is for sure if bitcoin is going to survive ,the price is going up every year because it is harder and harder to mine new bitcoins so until all the supply will be mined the price will go up a lot.

The rise in value is not one kind of fiat money has not increased by several thousand times in a decade. Online currency Bitcoin rate which is already over 11000 dollars apiece could easily multiply demand and rise in price

Look mate you are getting it all wrong ab possibly this is the effect people get after reading a lot of r/bitcoin or r/btc subreddits. Bitcoin mining does not work like that. Considering majority of miners stopped mining then the profit of mining will be distributed among those who are still mining and the difficulty will decrease. Also the hashpower which is currently in use by the miners, who would continue in this hypothetical situation would compensate for a large profit.

It is not about bitcoin cash which is a shill-pumped trashcoin made by a liar like Rogver. Bitcoin is here to stay copycats will die.

It is too bad you had to ruin a perfectly good post with slander. That is definitely the effect people get after reading a lot of r/bitcoin or r/btc subreddits.

The bitcoin structure makes mining difficult in time.That is, as the number of bitcoins decreases, the amount that can be subtracted decreases.

Investing is a pretty lucrative project that you can earn amounts the more you invest the more the amount.

Don't worry mining fees will exist every time. Just remember a few months ago, when BCH and BTC were 'fighting' and miners were hopping from and to the different chains to mine. This caused high fees on the BTC chain, so the miners earned the block reward and serious profit from fees as well. This amount of profit from the fees should be enough for the miners if the block reward ends,  so I don't think it's an issue .
