since bitcoin is a POW coin,what will be awarded to miners after the circulating supply reaches the maximum supply which is 21 million ,that is when the last coin has been mine

If bitcoin stay the same until that day the price of 1 btc will be very high and transaction fees will be the reward for miners who validate the blockchain.

but we don't know the future yet and there are many circumstances like hard forks that may come to bitcoin.

Transaction fees will pay the miners.  I suspect that if no new coins are being rewarded, or some time before when the rewards are very small, then there will be little incentive to keep building these beastly mining rigs and farms.  Or perhaps transaction volume will be so high that the rewards will still be significant, from transaction fees alone.  Keep in mind that although something like 80% of the 21 million are already created, it will be a very long time until there are no more mining rewards.  I think the estimated year is something like 2140.  But the block halving will make rewards insignificant before then (number of BTC will be very small, but it might still be worth a lot of money).

It will be a long time before we reach that point, and most of us will probably be dead if the year is 2140 or something like that. For the system to work, there must be a significant value to a Bitcoin, and there must be a significant amount of transactions so that fees can keep miners going.

it will probably pass several generations to reach 2140, we do not know what will happen in the future. but if the BTC survives and has reached 21 million then what will happen is the miners will be forced away from the rewards of the blocks they received for their work once the supply of Bitcoin has reached 21 million.

Mining will need to continue to handle all Bitcoin transactions. Fees will need to be collected as a way to pay miners and this will be the only source of payment to the miners. Therefore, it is possible that fees would need to be higher to support mining.

The good news is that it's going to take a very long time to get to that point. We will be long gone by then so future generations will have to deal with those larger miner fees.

Bitcoin will never reach 21M.  It will be dead long before that happens.

Although we will never hit exactly 21 million the block subsidy is set to deplete at block 6,930,000 which is estimated to occur sometime around the year 2140.

However, the vast majority of bitcoin (99%) will have been mined by around 2032, when the block subsidy drops to less than 1 BTC per block. Roughly 20.67 million coins will exist, leaving less than 1/2 a million to be mined over the next 100 years.

2032 is not far. I can only imagine bitcoin's value by then. To the moon.

The first bitcoin will never reach 21 millions supply, and the second the miners still run the nodes to secure the network without a reward from the bitcoin. But i think the transaction fees will be gradually increase as long as the miners will not receive the reward from the block again.

Then it will be the number of stock. Once that the bitcoins are purchased. There will be spikes and hikes in prices. It will not be purchased all because it will go through the circulation. Time to time bitcoins will be in exchanges. So there is nothing to worry about. The good thing about it is that prices will definitely increase.

How come you already know what will happen? noone know how much supply of bitcoin left.

Transaction fees will keep the miners busy once the last bitcoin is mined. But as the block sizing halves, the value of just 1 bitcoin may be worth many times more than what it is today, thus compensating for the decrease in rewards for miners.

Miners will be the earners when bitcoin was already been mined the drama will continue and I think value would be much higher since bitcoin really been recognize and potentials are so big being adopted by most establishment after this issue has been resolved from the Chinese.

Unless the btc price has risen greatly, hash will go down, network will be less secure.

Yes, it's doubt me too, so I suspect if btc can be come the real currency.

Well at that time there won't be any other rewards except for the transaction fees.
It's expected that all 21 millions coins would have been mined by 2030. That's not far. At that point will mining stay profitable ? Nobody knows.

Maybe the whole world will join bitcoins at that point that the number of transactions is so high and makes continuing to mine worth it. But it might also not be so fair.

If you take into consideration, full nodes that run now aren't rewarded in any possible way. Although they're seriously important to the bitcoin network. Before we start thinking about 2030 I guess some rewarding system should be implemented for those 6000 nodes that keep our bitcoin alive.

That's not true, you can check the total bitcoins on blockchain.info or here (https://blockchain.info/charts/total-bitcoins). You need to read more about bitcoin.

I agree more changes for bitcoin is expected to come in the future. Once bitcoin fees starts to become expensive there's a chance that people will start moving to bitcoin's counterpart. I hope that doesn't happen though.

Not really 0 but miners will still mine some satoshis or dusts before they mine the last whole coin.

The rules will remain the same, only the block reward will be 0

After the 21 milionth bitcoin is mined, the miners are done with bitcoin mining contract. So what's next? Miners would probably (and really) be paid with transaction fees from the bitcoin transactions people are making. Another is that, they might find new contract with other companies planning to create new altcoins or tokens.

We don't know what might happen because it is in the future. There are lots of possibilities. By that time, Bitcoin might be the Universal Currency and have a very high value. It is also possible that by tthat time, Bitcoin is fighting for its survival in the market because the people love other coins than Bitcoin. We can never assume anything.

As there won't be any more coins to mine then firstly miners will get engaged into confirming the transactions. As they won't be having any coins to mine then  that's the priority which would be allotted to them. Besides that the price of bitcoin will just boost very high. Due to high demand and limited supply that's going to be most amazing era with bitcoin equal to six figures of salary. Moreover, there might be another coin getting created like the bitcoin only and people may introduce whole new mining industry with that. Anything is possible with coming future and after the last coin being mined.

Some says that transaction fees would pay the miners. It would tke 100+ years for the last Bitcoin to be mined and the price of bitcoin would be really high by that time. Due to demand of the community on having some BTC

but cheapest  fee is one of the most features of bitcoin which many people have  interested in with bitcoin. the users of bitcoin will not satisfy again while they use bitcoin anymore due to bitcoin lost 1 most important thing.
if that's really happen, demands of bitcoin will decrease and we would not see the price of bitcoin increases.

Transaction fees will be the reward, it is a good bit away right now so who knows what the world will look like at that time, imagine if bitcoin really broke through and was the main global currency, the fees would be very much worth it.

There has already be bitcoin cash .I guessing they will do a hard fork a.They might be 10-20 fitcoin forks by that stage anyway so i wouldnt worry to much about it

It's still a bit of a long time until the last bitcoin will be mined, but after that miners would still probably continue to mine small amounts then eventually transaction fees would be the reward for them. The problem is how profitable would that be, and would it be fair. And would transaction fees largely increase in line with this.

After lost coin mine the part of supply will stop so if have many demand price will up

I think bitcoin price will become very expensive by that time. And yes the demand is also very high but I cannot say more as of this time. Because we will never know what might gonna happen in the future.

Hopefully, it will be popular and expensive enough, and it will just circulate up and down, people buying and selling with Bitcoin and all.

However, there can also be improvements to the protocol from them on...

The normal and most probable thing is that after no more bitcoins join the market the price will increase significantly I think that's the reason of so many holders.

In the long run we really can't even predict what will happen, but what I feel is they shall recieve the money from transactions fee as usual. Then also the price shall be so high,that It can be a collector item lol. So they may even put up bidding process, as we all know that's it's a long run we can't really say, with so many forks happening, anything is possible but one thing is for sure, miners shall continue to earn at our expenses.

If that thing could make the transaction fees go higher when at the same time the price of bitcoin is on its peak. I'd be suffering and be sure to not use bitcoin again. The current transaction fee which take approximately few dollars are enough to make me think twice before doing transcation.

If the last coin has been mine then bitcoin will be so expensive on its price because the supply is very limited since the supply is mined out and the only thing that we can depend for the supply is the demand for selling bitcoin in the market and that will make the price of bitcoin even more volatile and i think that it will not become a stable coin like other investment vehicles.

Then it becomes extremely profitable! Since it's scarce and there is only 21 million bitcoins you will enjoy the benefit of great rewards if you buy and hold now.

To get mined of 100% of the total supply, this will take forever mathematically. This is not like years, because it will converge to 99.9999% always.

There would be price inflation after the supply was mined.
