 With this one known fact about Bitcoin, my question is what happens after the limit has been reached?

After the 21 million Bitcoin limit is reached, Bitcoin miners will no longer be able to receive Bitcoin rewards for mining new transaction blocks.
The value of Bitcoin could increase, as the demand for Bitcoin could increase due to a scarcity of new Bitcoins available.  There may also be an increase in transaction fees, as miners will need to be incentivized to continue confirming transactions on the network.

When bitcoin hits the 21 coin limit, maybe the motivation to mine depends solely on transaction fees. And transaction fees are still there, but at that time they will become very important because they are the only source of income for miners and this fact was predetermined in Satoshi Nakamoto's whitepaper.
and once all the bitcoins are available in the market and people start using them to buy or pay, the number of transactions will be very high and mining will be required to do that. And miners will earn transaction fees for making that happen.
and if I'm not mistaken the last bitcoin is slated to be mined in 2140, and maybe all of us dead who won't know what happens next and for now only know the information that already exists which doesn't necessarily get there, and surely the price of bitcoin will increase substantially and transaction fees will be high enough to offset the fact that there are no more block rewards.

It's a hard thing to imagine for sure, almost like the bitcoin charts but I think, we would have more or less of a stable market, reduced mining services with no block reward to motivate them but, the fees would be all there is and by the dynamics we already have with the volume and fee, it just might be enough to stimulate the miners out there to keep up the job of fixing our transaction in blocks.

I would have expected the fees to be dropped to a minimum to ensure quick transacting and confirmations while, the bulk of the fees is gotten by the number or volume of transactions that could be confirmed in a period but, the future isn't here yet and it just might be better when it comes.

You might find more ideas for this thread if you spend a little more time on the forum. Simply click the search button and visit Google. However it's possible that we won't be alive when Bitcoin reaches 21 million and is fully mined. Who would have known it would exist before then? We are unable to make accurate predictions, not even knowing if we will survive. But if Bitcoin is still around by then, I have no doubt that its value will skyrocket. Miners will always support Bitcoin since they will continue to profit from transaction fees. When the number of Bitcoins reaches 21 million, the price will be very high.

I don't know how you think about it, I don't think the 21 million bitcoins will be reach because the Mining, buying and selling are all circulating around the the nods (blockchain) in the ecosystem, so when you buy Miners do their job, when you sell the same thing happened therefore bitcoin does not stable in one direction to reach the end, it always circulating around.
In other words, it is not possible to reach or mine the 21 million bitcoins.

I don't know if I understand you correctly, but the 21 million bitcoins can be reached. There is nothing to be said against it and it is only a matter of time. Current projections say it will be in 2140 and all bitcoins have been mined. Sure, by then more bitcoins will be lost and there will probably never be 21 million bitcoins in circulation, but they were mined nonetheless.

But what happens next is difficult to predict. Perhaps the bitcoin price will then become more stable, if it still exists at all. I don't think any of us here will experience that anyway.  :)

What happens when bitcoin mining reaches the full 21 million. Well, I think it’s pretty obvious. Bitcoin would get insanely valuable and the price would reach the high heavens. It may very well be a long time from today but when that time comes, and it will, the world would have most likely adopted bitcoin.
The price of bitcoin then would either become stable or go upwards. I thing I know; when that time comes, it would be a highly sought after commodity, and the increase in demand would only result in the increase in prices.

Why do you guys think that, once all Bitcoins are mined, the price will become more stable?

It's supply and demand that set the price.
On the supply-side it doesn't really matter much, if there's around 19mill, or 21mill in circulation, 'cuz there's only a few mill actually available on the markets,
the demand doesn't care at all if it's fulfilled by old, or newly generated coins.

So, what is it that makes the price more stable?

When all coins are mine, the block reward become zero but the tax included on that block will be the reward of the miner.  It means, the mining activity will continue since there are still transaction fee to be mined.  Satoshi created this kind of system to limit the inflation of Bitcoin and at the same time encourage the use of Bitcoin in order for the network to continue.

So I think if the Bitcoin adoption (Bitcoin usage) is very successful, miners will have the motivation to keep on mining because of the huge transaction fees to be mine.

From that point of view you are right. Of course, the price is determined by supply and demand. But by 2140, many coins will surely have been lost and large amounts of bitcoins will be held by few whales. These can reduce the supply, since no new bitcoins can come onto the market through miners. As a result, the price could be pushed up and also quite stable. But maybe that's just a wrong mind game on my part. Unfortunately, I won't live to see that point in time anyway.  :D

It's more of a symbolic moment when the last satoshi is mined rather than some big question as to what will happen. Because the mining reward will have been barely anything for decades leading up to the last Satoshi that for a long long time before that moment the vast majority of the mining rewards will be through transaction fees.


Now as to what will happen after that moment...nothing. Bitcoin will just keep working as it always has been for already around 130 years at that point.

Nothing of note will happen, the halving guarantees that way before all the coins are mined the block reward will become too small for miners to rely solely on it, so at that time they will depend on the fees paid for each transaction included on the blocks they mine, the miners that fail to adapt will go out of business while those that remain will become more efficient, so nothing will really change if you think about this.

After the 21,000,000 BTC has been reached, where will the miners' charge be deducted from? And how will that actually be of advantage to miners? Pardon my silly questions. I know little to nothing about how mining and its charges work.

If I'm not mistaken, I hadn't seen the season of threads with this question, on this board, that is, there are consistent questions that are repeated year after year, in short, one should ask an introspective question with reference to basic bitcoin situations, on the question of "no one will have asked this before".

 In my case, after going to Read about the subject, I can only say, since there is past intervention from users who answered your concern, it is better to go for shorter periods if you are only interested in "what could happen", then each 4 years is fine.  :)

This is an intriguing question that will cause one to assume or imagine it by then. However, the fact remains that no more bitcoin will be mined. The miners' reward for successfully mining a block into the blockchain will end. Bitcoin's price will almost certainly be much higher than it is now, and it will almost certainly be stable by then, with widespread adoption. Although these are all fictitious facts about it, few or none of us will be alive to witness it, but one of these events is very likely to occur.


After a block is mined into the blockchain for every successful transaction; for a normal wallet the miner earns the reward for it. However, if it is an exchange or custodian wallet service, the higher portion of the fees goes to the exchange and the lower portion to the miner’s as it’s shown on the blockchain explorer.

first of all.. lets just math out WHEN this will happen
6.25btc curretly and halving every ~4 years results in a reward stoppage in the year 2140

thats <120 years from now,.

but now lets pretend its 140 years in the future
knowing that just 20 years ago people thought 4gb hard drives were the limit. and now thing 20TB is the limit

data storage of 140 will be an far greater number by many 1000x factors
where by at that time its not going to still be only 2000 transactors pay huge fee's per tx it will be a magnitude high amount of payments per block paying a small fee. which all total up per block to be an amount healthy enough to cover good security level of hash difficulty for a block

yes there are some people that oppose having more transactions per block. but they are stuck in caveman mindsets that data is limited and will continue to be limited in future years.
much like how kodak said that digital photos wont work due to limitations of flash memeory/floppy disk spae in the 1990's
you know the 1mb limit of portable data back then means that photos of 1mb wont be useful if you can only transfer one at a time
that myth got busted as soon as 1gb portable memory was available and then several gigabyte then terrabyte. all within 2 decades

so imagine in 2140 there would be several magnitudes more transactions per block thus not needing each user to "pay more" but allowing more people to "pay the same" which totals combined gives more to mining pools

and no it does not require transaction counts to leap to 1000x today. but also we should not be delaying transaction count increases on-chain to be held back for decades either
it can SCALE (progressive) increase as time passes.

the strangeness of the debate about transactions per block scaling. the opposers of increased tx count are weirdly adoring and promoting that the current 4mb space should be used for stupid meme images and not transactions.
so its obvious they dont care about bitcoin being a payment network with natural growth scaling of transactions. they just want bitcoin to fail so they can promote whatever other scheme/network they prefer people to use as a payment network. they simply dont want to see bitcoin as a payment network of most users

All people above me already said what will happen when bitcoin reaches its limit but i want to add more when its reach limit bitcoin circulating supply will top and maybe the price will crazy although its not gonna 21 million since there is address or forget private key maybe around top 20 million that in circulating. the miner depends on transaction fee meaning the big mining farm maybe close their rig and run small farm and the block difficulty will fall down although

The year 2140 most of us will probably be dead already unless you have a potion to keep your life immortal and see bitcoin on top.

How is the 21 Million Bitcoin Cap Defined and Enforced? (https://blog.lopp.net/how-is-the-21-million-bitcoin-cap-defined-and-enforced/)

After 21M total supply is reached, miners will earn their income from transaction fees.

In technical, 21M total supply can be changed but who will support that proposal. Increasing total supply of Bitcoin is harmful and it won't bring benefit to anyone. It's harmful because people have solid reasons to think that if total supply can be changed one time from 21M to assumed 42M, it will possibly be changed again in future to like 84M or 128M.

Side effect is people will lose their belief in Bitcoin and its protocol and price will not have reasons to grow more.

In that distant time there will be many great changes that have taken place, some of which we can imagine and others we know nothing about.

For example, one scenario is that the price of bitcoin will reach a million dollars at that distant time in the future, and therefore the small fees that miners receive in satoshi will have an attractive value to continue their work.

Another scenario is that whales that own thousands of bitcoins will play an important role in maintaining the stability and continuity of the network by covering miners' fees, because if the bitcoin network collapses, whales will lose billions of dollars.

If we are using a rough calculation, the last stock of Bitcoin was probably mined around 2140 .  When the last Bitcoin has been mined and there are no new Bitcoins, the Bitcoin mining process will be finished.

 Even though the Bitcoin supply is running out, Bitcoin miners can still profit from Bitcoin.  This is because Bitcoin transactions that occur on the blockchain network will require a series of verifications.  So, the miner's role will shift as the party that verifies the transaction.

Who told you that? Don't listen to them anymore.

Even when the last Bitcoin (or rather satoshi) has been mined, the mining process will never be finished.
The only thing that's finished then is the initial distribution of coins.

no mining = no new blocks
no new blocks = no transaction will ever be "confirmed", they would be stuck in mempool forever

So, if people want bitcoin transactions to work, someone needs to mine blocks, no matter with or without generating new coins.

Bitcoin mining fees will disappear when the Bitcoin supply reaches 21 million. After that, miners will likely earn income only from transaction processing fees rather than a combination of block rewards and transaction fees.

After the Bitcoin supply hits its maximum, no more bitcoins will ever be produced. The only anticipated source of income for bitcoin miners is from transaction fees.

The effect on Bitcoin miners when the cryptocurrency hits its upper supply limit will likely vary depending on how Bitcoin evolves as a cryptocurrency. If the cryptocurrency blockchain handles a sizable number of transactions in 2140, bitcoin miners may still be able to make money solely from transaction processing fees.

So you are assuming the block limit will be increased? I don't think that is a good assumption to make, just because that requires hard fork and at least right now not doing any hard forks is kind of the culture of bitcoin. I think mostly just because doing one hard fork opens up the idea of changing things more drastically and opens up the idea that Bitcoin isn't immutable.

I mean it would be good in the future once internet speeds are much greater and when having like a 100 TB hard drive is cheap if Bitcoin would be able to handle more transactions...BUT handling more transactions on-chain isn't a real solution. Because even if you say 50x the block limit, that still wouldn't be anywhere enough to handle mass global transactions. Now, yes, it would help miners as having that many transactions would totally resolve any idea that mining profits won't be enough once the reward ends, but mining will work itself out anyways as its a self-adjusting system. The question then is, do we want to make Bitcoin mutable in order to enlarge the blockchain greatly but still not be able to handle mass usage. If it doesn't actually solve the problem why would we do it which would cause more issues?

This was decided back in 2017 with the block size war and those who wanted a centralized high-data altcoin made their large blocks and left to watch their money disappear. L2 is the solution to mass transactions while mining will work itself out since its a self-adjusting system. So there really isn't a need to do anything, and thus Bitcoin stays immutable and safeguards one of its most important and unique aspects.

Mining will likely eventually shift almost entirely to business who operate directly at power stations and get very cheap energy while getting rid of mass energy waste in the system and greatly enhance the energy infrastructure of the world all while keeping mining costs very low, and people/companies/governments taking advantage of stranded energy to also mine very cheaply. Thus even if the mining income goes down greatly the cost should also go down and even if hash power likely hits a peak at some point and then falls we have to realize Bitcoin mining is ALREADY globally secure and nothing could ever attack it as long as mining stays decentralized globally. So if hash power increases for a few more decades and then starts to drop to a long term equilibrium that is fine because  Bitcoin's security will still be far in excess of what it is today, miner's will make their income, L2 will handle millions of transactions, on-chain transactions should still be cheap enough for moving money around or making large transactions, and Bitcoin will remains immutable and therefore secured for permanent viability as hard global money.

actually the latest motivations is to change things without a strong consensus consent. changing things without nodes being ready for said changes.. which is more riskier and bad network security
the reason they do it is because doing it the proper hard way, means core would not get to throw random crap in easily. so they wanted a back door
and look what happens. the tx count is decreasing and the bloat of stupid memes abuse of space is increasing.. risking the utility of bitcoin remaining a payment network with this stupid backdoor policy


your argument is keep things low for 120 years. or leap to 50x this year to be one world currency?? (facepalm)
actual reality is neither
its progressive scaling over time. not 'huge leaps today or never' approach you assume



actually its more about when new power generators come online they are not built just for todays demands they are built for demands of the next 50 years
meaning demand:capacity in the initial years is 1:4 meaning current demand is paying 4x to cover yearly cost of re-reimbursing the build cost
however mining will move into a region and buy up allotments of the excess 3 ratio thus bring down the average cost per kwh due to more income for the power station. and over the decades as more native residential/industry demands want to use more of the capacity. miners would move their asic shipping containers to the next region offering spare excess capacity on their new build power generation


L2 does have a place. but the current prototypes and concepts being played around with have flaws and only fit small niches
ther will be development once the snake oil salesmen of current concepts realise they are chasing their own tail on flawed design. and development then start moving away from those concepts and come up with better ones.

but while that happens bitcoin needs to scale too.
if you think bitcoin should remain at a 2000 tx per block for 120 years. you are not thinking hard enough
and no... jumping to 50x in the next year is not the option either

de-cludging the currently allowed 4mb to actually allow a 4x scaling compared to the 1mb limit would bring tx count from an average of back-then 1600tx to a plausible 6400tx a block

then say for this posts demonstration sake, every 4 years is a 4x factor(reasonable scaling)
(not your silly 50x)

after all 20 years ago (5 scale periods)
we went from
harddrives of 4gb to hard drives of 4tb (1000x)
56kb internet to 56mb internet (1000x)

so basic math
   2023                    2024                      2028                 2032    
4mb(6400tx)   16mb(25,600tx)   64mb(102,400tx)  256mb(409,600tx)

   2036                  2040    
1gb(1638400)   4gb(6553600)

and as you can see thats the 1000x over 20 years we have seen tech scaling previously. thus able in future

remember we already have 1gb PER SECOND internet available now. thus will be the norm in 20 years
meaning a 4gb per 10 minutes (600 seconds) wont be a issue by then
4gb per 600 seconds is (6.72mbyte/sec =53.76mbit/sec - again achievable in 20 years, becasue its achievable now)

also if we factor in an assumption of whole population wanting to lock up value each month(like debit/credit cards) meaning 2 payments a month(lock and unlock to rebalance)

6553600 * 4032 /2 = allows  13,212,057,600 (locks+unlock combined) a month
by which would be the population base of that period

however sticking to 2000tx a block (for those 20 years) means only 4,032,000 rebalances of L2 a month.
meaning if there are 200m users(low ball number). they can only rebalance/move onchain. once every 50 months.. 2bill population =500month rebalance
no one can plan that far ahead their daily spending.
and thus if you want to promote that people should lock up value in a alternative system to bitcoin for 50 months. then you are trying to suggest that bitcoin should not be a payment system or a currency.

people would just end up using a different mainnet and not even bother with bitcoin in the situation you prescribe

and that is why bitcoin should scale onchain aswell we create NEW l2 that actually work and do as promised. instead of the current paradigm we are stuck in with silly people just saying "be patient"

Not sure where you got the idea that I said there would be a 50x blocksize increase this year.
I didn't say anything about a single limit increase nor when such a hypothetical increase would happen.

Seems like you are just trying to put words into my mouth so that you have something to put down.

I was using 50x as an example, the point of which was that even if in the future at some point bitcoin blocks were 50x larger (or whatever amount larger you want to use as an example) than today we'd still need the same L2 solutions we need at the current block size. So that kinda shows the flaw in thinking larger blocks are needed, because they won't solve the problem of transaction capacity. Only L2 can do that. Which is why the ideas behind the crappy BCH and BSV were rejected.



And as I was saying one of the most fundamental, important, and unique things about Bitcoin, one of the things that makes it great money, one of the reasons why every single other cryptocurrency would make terrible money, is that it is immutable. If hard forks start getting implemented that kills the idea of Bitcoin immutability. It opens Bitcoin up to anything being changed. I'm not saying there can't ever be any hard forks, as there MIGHT come a time or two when Bitcoin does need a fundamental upgrade, but that would be a dangerous thing and it should only be done if the only other option is something terrible happening to Bitcoin. Since block size increase wouldn't actually solve anything because regardless of blocksize Bitcoin would still need L2 solutions for mass usage, block size increase seems like not a very good reason to hard fork.

Obviously blocksize COULD increase over time as internet speeds increase and much larger hard drive sizes get cheaper, meaning much larger blocks wouldn't hurt decentralization. And yea this would allow a bit more mining income once the reward gets real small and it would allow cheaper on-chain transactions. But the main reason to not do it is that it'd kill Bitcoin's immutability. So that sort of thing should only get done if stuff like fees and feasibility of mining actually become very dire and threaten the viability of Bitcoin. Which may never happen, and it certainly won't happen soon. And presumably in the far future L2 will be heavily used so that the on-chain tx fees won't get super high. And mining being a self-adjusting system won't likely ever be in peril though I suppose there is a bit of worry that income would get so low that it could actually hurt Bitcoin's decentralization but that certainly isn't a given.

This has been discussed too many times if you care to search about it and you will be directed to different threads having same discussion about what happens when we reach 21M coins supply.The answer always remain same that the miners will be encouraged to keep the network secured with transaction fees only but still we are talking about period of more then 100 years so we can only make predictions and actual results will be out then only.So hold your coins for long period if you can.

it wont kill bitcoin immutability

hard consensus does not delete old blocks. old blocks remain. the immutibility is sustained
thats the whole point

its soft consensus that allows rule changes without nodes being ready to perform validity checks

please learn some basic concepts it seems you are just reading old propaganda crap from 5+ years ago

changing rules. hard or soft is about future blocks.. thus nothing to do with immutability( existing blocks)

though yes some idiot can completely do stupid things like make their node reject any block containing for instance legacy tx. and then doing Initial Block download.. thus rejecting every block. but then they are just rejecting their own blockchain acceptance and throwing themselves off the network

---

soft= new stuff activates without majority nodes requirement to being ready to fully validate the new stuff because they just stupidly accept new stuff as valid without checks

hard= nodes need to upgrade to be ready to validate new stuff before the new stuff activates.

learn the risk options that occur when going soft. where things get added to a block and treated as accepted without nodes checking/verifying/validating it as acceptable.. by blindly accepting it without consent/choice/check


hard consensus requires majority of node agreement(consent) before changes activate
soft does not require majority of node agreement(consent)

its the soft you should be concerned about..
.. take some time to think about it

As already said on this thread, the last bitcoin will be mined in 2140, which is 117 years away. This question will only be answered in 2140 when there won't be any reward for miners in terms of bitcoins. Defiantly, there will be a reward in some other form for Miner who are putting their efforts in securing the network. Otherwise, no one will voluntarily pay for electricity and buy expensive devices just to keep Bitcoin network secure.

The worst thing that is in my mind is that there are no more miners and probably there will be no more bitcoin transaction validators because they are no longer getting the new bitcoins they get as their wages, maybe they will stop being interested in bitcoins? I personally what scenario will be carried out in the future and what will it be like if a maximum of bitcoins is already on the market, but to reach 21 million coins it takes tens of years that maybe we can speculate at that time and we cannot predict that era with the thoughts we have have now.

Once 21 million Bitcoins are produced, miners' block rewards will only consist of transaction fees.

Once Bitcoin reaches the 21 million units limit, demand for the Bitcoin network may increase due to limited supply. This could cause the price of Bitcoin to increase. On the other hand, transaction fees may also increase, as block rewards will consist of transaction fees. This could make it more expensive for Bitcoin users for lower-amount transactions.

However, it is difficult to make a clear prediction in this regard, given that there is much more time before the 21 million Bitcoin cap is reached. Also, the Bitcoin protocol could be updated to address scalability issues as needed to respond to this situation.

When all 21 million Bitcoins have been mined in 2140, mining rewards will cease, and the only source of income for miners will be transaction fees, which are expected to incentivize miners to continue securing the network.

The impact on the price of BTC when mining stops would depend on the supply-demand dynamics at that point in time. With a fixed supply and potential demand, the scarcity of BTC (https://www.sanalsavunma.com/bitcoin-btc-pioneer-cryptocurrency/) could potentially increase its value, but it ultimately depends on the overall adoption and usage of BTC in the future.

Additionally, with the widespread adoption of Central Bank Digital Currencies (CBDCs), trust and access to digital currencies like Bitcoin may increase, so BTC may potentially gain significant value during these dates.

After all bitcoins have been mined, there will be no more bitcoin to mine. Miners will no longer be rewarded for successfully mining a block into the blockchain; instead, they will only be rewarded for confirming transactions (transaction fees). The price will most likely be x100 of what it is now😁. About the price is just a mere speculation, we can't really tell what the outcome will be by that time, but I'm sure none of us alive today will witness it happening, and my reply today will be live until that day to see.

CBDCs may have the edge over cryptocurrencies, as they would be regulated by the government and be more stable and reliable.  But Bitcoin offers privacy and decentralization, which CBDCs could never do for their part.

The last bitcoin is expected to be mined by 2140. None of us will live to see that time, so we will never know the answer to this question. Already, according to various estimates, from four to six million bitcoins have been lost. This figure will constantly increase, although perhaps not at such a rapid pace, since, due to the high price of bitcoin, its safety will be treated more frugally.
But no one knows what might happen to the cryptocurrency in another hundred years. Perhaps by that time bitcoin will completely change the current issue will not be relevant.
