It would be great collapse for millions of miners (

There are only 21 million total bitcoins that can be mined, what will happen if all bitcoin is already mined?

I don't really know the exact answers but im hoping that this bitcoin will become a global digital currency in the future that we can use wherever we are and whenever we want. I think if this bitcoin reached its total maximum of 21 million, it will stay for long and the value of it will become constant and sustainable, maybe the other coins will surpass this bitcoin in the future but bitcoin will not stop.

[tiger2monkey]

It will take long time to mine all of the 21 millions bitcoins (~20 years), which means that bitcoins will survive for long time. By that time, bitcoin price will be much higher and the usage will be high also. Miners will continue to mine and secure the bitcoin network as miners earn transaction fees (even though no more block reward, but transaction fees are there).

Also during this 20 years, bitcoin protocol will evolve.

Think about Fed or other Central Bank. They can print money whenever they want - and control the "local" economy jusy by adding extra cash in the system or lower the interest rate. As a matter of fact the value of its money is cheaper so citizen can spend it more. BUT be aware that system is controlled by an authority!!! Are you sure you can trust them ?

When the money printed is too much the entirety economy goes down because of inflation of hyper-inflation ( see what's happening in Venezuela ) and what you own is just a bunch paper with some ink on it.

So thanks to its definited amount ( 21 MBTC) , BTC will never be influenced by inflation and yet it can only growths its price.

The issue is that profits from mining new bitcoins is continuously decreasing (and will reach 0 in 2140, when all bitcoins have been mined), while cost of mining is increasing. So to keep miners mining (because without miners the whole system breaks down), they need to be paid somehow otherwise. This is where transaction fees come in, but it's in my humble opinion also the most problematic part (next to lack of scalability) of bitcoin. The more you pay, the faster your transaction will be processed, the less you pay the slower (or possibly never if you are unlucky) is your payment processed. This means for your payments to be timely processed, you'll have to pay a sizeable amount of transaction fees, as you don't have a guaranteed transaction time, but have to pay for it. Just imagine you: timely pay your rent, but don't pay a high transaction fee (possibly because you simply can't afford it) and get thrown out of your appartment, because the transaction was simply not processed (or not fast enough) because of it and you not willing (or able) to pay a premium for fast processing. So in a very problematic situation you might be forced to offer transaction fees, that would make the interest of a loan shark look like a good deal, just to make your payment work.

Yeah, but not all of them because some miners will be required to process the transactions which will be a lot by that time, I guess

[JayT22]

i think btc will increase  all the time until a crisis hit the world.mining will take longer than the world maybe exist how we know it  now!!!

[yohan09]

If all bitcoins are mined, I guess the demand will rise up and the value follows, As expected second rank of alt-coin rises and generally will dominate blockchain industry. Before 2140 happens, Precisely i find myself in other space, At this moment i just enjoy the benefits, of gaining good profit for my daily needs.

you are right in don't thing it will happen we need to incres the supplay as demand increases. If bitcoin completely miners will bother about it. They only get income from the transaction we are doing from the one wallet to another wallet.

many speculators are expecting it to be mined in 2050 itself. As you said, if it is falls on 2140 I too really happy.

[daserpent]

Bitcoin is coded in a way that miners will earn rewards from fees after all the bitcoins have been mined.

By the way, the 21million Bitcoin limit time is far away... not something we should worry about right now.

Last bitcoin will be mined in 2140 according to the code. Which is 123 years away from 2017.

By that time, we would have gone through A LOT more

[ramyon]

it might be possible to arrest businessman bitcoin business because at the next gap take

[logicgate]

Then bitcoin will SUN no longer MOON

That is so true. Exactly the definition I want to say, you said it all. Nothing can make bitcoins more useful than this mined bitcoin. If all the mining is already done with bitcoins then there is no such limit of use and bitcoins are so easily treated, more than now. So you said it right that after that you will be seeing bitcoin on sun.

That is actually a very good information for all of us still a long journey ahead to mine all the bitcoin at thet time ae may passed away.When the number of bitcoin have to be mimed decreases the difficulty level to mine that bitcoin will increase so we don't have to worry now.
Then i will answer for the topic now when the all bitcoins mined the bitcoin price will reach very high maybe $ 1000K or more.Bitcoin holders are gonna be millionaire and the transaction of bitcoin take less time than now.No one can predict the future so let's wait and see.

[cipher-x_09]

I am sure the developer will do something about it before it occurs but if it really does happen then I guess miners will not have something they can earn or invest on. But as a business analyst I there is always a contigency plan for cases like these.

[Red Fish]

Answer is simple, Bitcoin price will go up. And altcoins will be more and more popular, especially most popular, like ETH. In fact, I think, that ETH and Ripple price will also go up, when all Bitcoins will be mined.

According to research if bitcoin reach its limit, it will be disappear but it doesn't happen already so don't worry. I think devs will solve the problem to extend.

.

Oh that's a worrisome facts. If all bitcoin are already mined, it will be disappear? Oh my God! i am so really worried about this. hopefully, dev will get a solution for the future problem. 

[raygchannel]

The network will run on all the transaction fees that are required to send your bitcoin over to another bitcoin address. But that will atleast take another decade if I'm not mistaken. I wonder how big bitcoin will be at that point in time. Perhaps everybody is using bitcoin then.

Disappear to where? What research? simply state that this is your uninformed opinion. For starters, the blockchain will still be there so bitcoin is not going to disappear. Secondly, only worry of for miners as there will be no more block reward. But they will be sorted as they can still earn through transaction fees. But I think this will require the devs and bitcoin community to make changes on the blockchain. My 2 cents.

[Xenrise]

If all bitcoins were mined, then the case would be this: the demands of bitcoin will go up and if you are to look on the supply of it the circulating supply is high and so as the price would be high also .
