Bitcoin has a limit to the number of tokens it will release. That number is hard-coded at 21 million. The estimated date of Bitcoin issuing its last coin is believed to be in the year 2140. No one can predict what will happen at that point, but miners will always earn some profit from transaction fees. Plus, users of the blockchain and the Bitcoins themselves will be incentivized to protect the network, because if mining stops, Bitcoins become vulnerable and so does the data that has been locked into the blockchain.

I believe until there someone will have developed an option to make it last more time, even today there are people already trying that, and new alt-coins being born from such discussions.

I'am agree with your statement , until this day I can't understand if 21 million BTC has been create from miner.
I think cost for send BTC will be expensive , because hasrate its very high.

Thats a long way to go. And even if the miners stop mining Bitcoin and it becomes a threat to the safety of Bitcoin network then the Bitcoin devs can always shift to a different algorithm like Proof of Stake or whatever new innovations are made.

There is a possibility that it can. 21 million is the number of total supply in the world and it will last until hundreds of year to mine all those 21 million. That is lot of amount by the way, it is gettinv harder everyday. If the supply runs out, good luck.

Nothing will be changed.
Now only 12.5 bitcoins are generated in every block. Compare it when the number of generated coins was 50. This number has dropped by 37.5. Is the mining stopped?

Do you really need to worry about things that will happen  after your death ? 2140 is really very far and bitcoins might not be able to survive by then. If you are still interested in the answer, if bitcoins survived till the last coin was mined, it will be because it becomes a commonly used payment option. And in that case, I see the demand only increasing more in future. Since the supply will reduce as no more mining is done, prices will move up faster.

You asked if Bitcoin will collapse upon reaching 21m coins, you knew that it will happen in 2140, then said no one can predict what will happen.
Why the hell you still ask for other's opinion if you already answered your question.

You said that no one can predict what will happen next but your assumptions will really make Bitcoin collapse?

dunoo , but my opinion bitcoin price will get higher
i have experience about some coin that stop their faucet , and burn their coin to get max supply , 4 month after , the coin rising up from 0,2 to 20-40  $
and i think it will same with bitcoin

Bitcoin based on the experts will not collapsed even though it have already reached its maximum or already fully mined, besides it will took more than 100 years before it happened and when that moment comes for sure bitcoin is already have a big name in over the world.

I think it will not be possible in a short span of time. Mining only provides a very small value. A year will only give you a small amount which cannot even deduct 1 btc. Mining isn't that gallant that it can give enough to those who looks for free bitcoins.

If Bitcoin made it to 2140 for real, that would be unreal and I think beyond most of our expectations here. Hard to believe any industry can go that long without being changed, but finance did it before for over 200 years perhaps it can happen again. Dont rule it out is all I am saying.

Miners will make money from transaction fees still, so it shouldn't collapse. They should continue mining to keep the network secure, and people will still run non-mining full nodes as a hobby or for their own security.

2140 is a long time away though. If Bitcoin is popular 120 years from now, there's no way it would resemble the Bitcoin we know today. Developers are already working on ways to have instant transactions off chain, with many other people running nodes to test out this technology. Then you hear about many other ideas that aren't yet being worked on. A lot can change in 120 years.

I understand that miners will still get miner fees from each transaction, but will that be profitable for them? I really doubt. For example if miners received only transaction fees and no block rewards today, it would not be profitable for them today. The electricity would cost more. And we all want transaction fees to be low, because bitcoin is useless if fee for one transaction is $20 or more. That's why services like Lightning Network are being developed to reduce fees even more. So how is this going to be profitable for miners if the fees will not increase dramatically?

Even after the completion of mining of bitcoins, there will still be need of miners to complete transactions through bitcoin and if it is used by the people for their daily transactions there would still be profitable in the mining business then keeping it still invulnerable and preventing it from collapsing.
Of course, it can not stay as an asset of earning by HODLING forever. There will come a time when it will be used for the purpose of its creation and that will also prevent it from collapsing.

What about IOTA? There is nothing like that but it is not collapsing. It is not incentivizing miners since they don't have one. Yet it is not collapsing. So what happened to your half baked thoughts? It's collapsing.

If bitcoin releases 21 million bits of mine I think the miners will move on to the other coin. The value of bitcoin will be quite high because bitcoin has limited quantity and transaction fees will be quite high.

I think that nothing will change because as it gets to the last bitcoin there will probably be a high price and it will not change.

Bitcoin will not collapsed after 21 million coins are mined. This is one of the fears among bitcoin users as if this is the end of the world for bitcoin. But let us discuss two kinds of things wherein miners would earn; first from mining bitcoins and second is through transaction fees. This would mean that even all of the bitcoin were mined miners will still work and their work is to process blocks of transactions and confirm it to avoid double spending. Thus even if all bitcoins are mine bitcoins will still be there and we can still continue to enjoy using it.

Once all coins are mined, I think the price will increase. However, there are many years for this to happen and I think bitcoin will not survive till then.

By the time the BTC is exhausted, the BTC should be the digital gold. So I don't think we need to worry about that.

Bitcoin is new money for millennials. It will not be used by majority of world population not to say about store of value function. In my opinion Bitcoin was experiment. It will not have any value when governments will find out how to track and control your BTC.

If one owns 10 BTCs in 2140, each BTC being £1m, thus value of owning 10 BTCs = £10m, these owners are going to mine/run a full node, in order to protect the network, regardless of block reward. It's blooming common sense. Do not panic at all.

After the 21 million coins are mined that would mean an end of supply of bitcoins. This only means one thing, demand will keep growing while supply will halt which will drastically increase the price of bitcoin.

First point, worrying something that is least to happen 122 years from now. (For sure we are totally decomposed that time)

Second point, given that all bitcoins are mined, meaning they are in people's possessions, and it will only revolve around people to people to people. People are mining bitcoins for future use they wont keep it and let it be kept until all people who owns bitcoin dies. Right?

Third point, technology continuously developes , with due respect for the present technology, in 122 years it will change and i know that it'll change for the better. Great people will still exist, and they will not sit down and watch the downfall of every technology that is created for the benefit of the people.

The last coins will be mined in about 122 years from now, so we don't need to worry about it. For heaven's sake, there is no guarantee that the human race is going to survive until 2140.

I believe it could happen. When people could no longer be able to gain, surely they will be selling their bitcoins because holding it would mean nothing. It will then go back a value somewhat a bit closer to the maximum value then goes stable with nobody gaining much. Unless people will jump to other currency leaving bitcoin value to drop even more and the volatility will then again play a role for it to become worth investing.

Supply will gradually decrease with every four year halving and will ultimately become zero when 21 million coins are mined. But that figure will reach in 2140. After that Bitcoin will have negative inflation. A deflationary currency will naturally has positive price movement. Since, demand is expected to increase in future, the limited and no supply will give the positive price curve. There won't be a collapse due to 21 million bitcoins being mined, but it might happens because of the no utility or intrinsic value.

Bitcoin reaching it hard cap of 21million will not collapse at all. Just imagine when bitcoin hit it's all time high of 20000$ ,it becames scarce (limited in supply and higher demand )and it also increased it values , awareness, more acceptability,
more recognition ,more applications into business, etc. world wide .Again Minner may not stop simply because Bitcoin has reached it's hard cap 21 million because, at that time,there must be control put in place to monitor every transaction that come into the block from everyone using bitcoin for various reasons and purpose. In a nutshell, miner will always there to over see that every transaction that come into the block are genuine .

A long way to go! Isn’t it unnecessary to think over those things which will happen when you will be no more probably!

yes it can be.
but how if the develop supply the coin?
you know that bitcoin have name, popularity. im sure many people want bitcoin long live. but if no, i think the other crypto will replace bitcoin. but we dont know about thw future. just do right now,

Demand for block space = miner income. Even with how LN operates (an off-chain application), it still depends on block space at the beginning and the end, because opening and closing channels require entities to pay an on-chain fee. Combine that with plenty of standard on-chain transactions, other tasks requiring block space, the miners very likely won't have anything to complain about if the price continues to go up. I wouldn't even be surprised to see miners scoop up at least a few BTC in miner income per block, which has already happened last year. I have seen 5BTC block fees go through due to the insane demand for block space. Sure, the hype of last year and an massive spam attack did their work too, but it can be seen as a sneak peak of what things will look like later on.

I believe until there someone will have developed an option to make it last more time, even today there are people already trying that, and new alt-coins being born from such discussions.

For a currency to fail it either experences recession or if it explodes. Yet for now in order for bitcoins to work miners regulate and control transactions. In return they get new bitcoins. When its all mined that wouldn't simply work so either it will collapse or the system will change the bitcoin will be regulated and centralized and we will have another partner to control the transactions meanong that the whole structure and concept of BTC will have to change.

Well it’s a long time, and a huge amount. It’s quite impossible to predict something of that distant range. Greatest thing about technology is it is always open to better technology to take place. For now, chill buddy.

Wouldn't all the coins being mined cause a surge in demand instead because people will know that there was no way to get any more bitcoins without buying? Which would just increase it's price and value?

Mining coins doesnot determine if the coin will survive or not,  and remember that miners don't only benefits from generating now coin but miners also benefits more from all our transaction we carry out every seconds on the blockchain,  generating the entire 21m bitcoin will not stop companies from still mining the coin,  this means that bitcoin cannot and will not go anywhere even if all coins are mined.

Well, surely the bitcoin is being mined, we have nothing to worry about in the near future because it will still be relevant.

Another bitcoin hardfork will solve that issue. The possible thing to happen is that bitcoin mining will still continue and the payment for miners is the transaction fees.

Or. There will be additional 21 million bitcoin.

 I think that only we influence the fact that bitcoin will live our activity and our interaction with it will respond to us in the future.

I think 120 years is enough time to find a solution to keep BTC alive even when all coins are mined ;)

But that is the future which most of us will certainly not be able to see and therefore is quite irrelevant what will happen then.You should focus more on the next 10-15 years because somewhere around year 2032 almost 99% of total BTC supply will be mined-and that 1% will remain for the next 100+ years.Therefore, this "problem" is actually much closer than most thinks,but also this means that at that time(2030) there will be very small amount of fresh mined coins on market,so if demand be significant-price will follow that for sure.

Accurately, it is not 21 million, as you said it is the total supply of Bitcoin and there are millions now in circulation that means 21 will not be mined. 16 million is mined and only 5 million is remaining, there might be a lot of miners in the world but the mining process is getting harder and harder every year, we don't expect it to happen that quickly.

For some reason it seems to me that only the government if it can stop bitcoin will suspend it forever. Not so simple as it would seem.

No. Bitcoin, just like any other currency, needs circulation in order for it to have a stable value. After 21 million coins are mined, bitcoin should have a balanced abd stable value that needs to be maintained by circulation of the 21 million coins that are mined and are bought. Lastly, as a result, the value is expected to not rise or drop but be stable for a couple of months until it reaches a higher amount kf users.

Bitcoin is free of all currency and it can exist for a long time on its own until the developers themselves change their minds about it.

 Well, surely the bitcoin is being mined, we have nothing to worry about in the near future because it will still be relevant.

Today we r living in the year 2k18 and in this year there is so much fluctuationin the valuation of BTC and people are worring about the year 2140, I think this is the foolishness if someone is thinking about that far future when the BTC will stop being mined and there will be no BTC to be own. First of all, I think this condition is next to impossible and if the worst will happen then  alsopeople will get profit, so don't worry and just enjoy your bitcoining.

I don't think we need to worry about that right now.
Because if all of the bitcoins are mined, then I'd like to switch to the POS mechanism,

the logic is that the more miners will always be added to the supply of bitcoin coins by itself as more and more are interested in the assets or something that is on offer will always increase with the increasing number of needs. if indeed it will happen as you say (depleted coins) will happen the name of inflation with a very high coin prices.

As of this time only 20% or 4.2 millions bitcoins remain to be mined. And i am fully confident that bitcoins should become more valuable over time after 21 millions have already been mined. There will be no parallel devaluation. The awarded transaction fees for bitcoin miners will keep the bitcoin system afloat.
