What happend 2140 all BTC are mined

[ballexplorer]

What happens in 2140 when the last BTC was mined with the confirmations of the transactions in the blocks and thus with the block rewards. There should not be more BTC than Rewards, because 21 Mill BTC were gemined.
How are the transactions then confirmed?

bitcoin will have moved to pos by then.......... dont worry about it since you will be less worried by then too i expect

there are tx fees left to allocate after mining is done

[butka]

The idea is that once the majority of bitcoins are mined, the sum of the transaction fees collected in a newly mined block would be enough to cover for the mining reward. It is not an unrealistic scenario given the current transaction fees.

[bitmover]

Theoretically there will not be any big difference (like changing to pos or anything like that).

As butka said, transaction fees will be enough for the miners.

As halving is already going on, block reward is not that high as it used to be, and we didn't moved to PoS.

As 2140 is a very distant future, by 2021 block reward is going to halve again. That will be an interesting moment to watch. Probably price will go up as there will be less bitcoins going to exchanges.

I also see that the price of the BTC could rise, if their will be less BTC going to the exchanges and the BTC will be shortage                                                                                                       

Whether the transaction fees then for the miners sufficient, will show.

Unfortunately, the miners have had disputes in the past because of the amount of transaction fees. That's why we already had some hard forks with the well-known result.

I also like the BTC as a payment coin. He is a piece of personal freedom for me.

Something tells me that it will happen in some popular museum, where visitors will be able to explore the evolution of money from seashells to the Bitcoin.

[mast3rm1nd]

we will be dead so it's not our problem ?? it's our kids' problem lol. I read somewhere that the transaction fees will cover the reward for mining. and that is interesting to see because the mining reward keeps getting small and the transaction fees are big as they are so maybe there will be a compromise somehow.

[amishmanish]

By 2140, Most small transactions should have migrated to using some variation of a second-layer solution like LN. Most on-chain settlements would be bigger transactions for which the parties will be willing to pay a good amount as fees for confirmations.

If sufficient distribution and decentralization could be ensured, we would have moved to a more open and free market with little scope for political motives determining availability of economic opportunities to people and countries. People would be much freer to monetize their skills if they choose to from any corner of the world. People would also be free to do more good for the poor. We will probably have a sharing economy.

Mining hardware would be advanced enough for anyone to contribute to the network without worrying about breaking even. The selfish motive would be replaced by a different understanding of what money is.

if bitcoin fully mined in 2140, then it still have a long time.
when bitcoin circulation cannot be added more, the value of bitcoin will more and more expensive.
but who gonna hold bitcoin for 100 years more ? we all could sell it in the future.

**based purely on current fees per block(~1.5btc)..
we could see the importance of reward:fee  flip to  fee:reward happening around 2029
where pools care less about the reward and care more about fees

the pools will continue to mine blocks because they get paid via fee's from transactions

*note dates are variable because blocks are not solved at exact times of 10 minutes(2016/fortnight)
for instance the january 2013 halving actually happened in november 2012 and the 2017 halving happened in july 2016. the next halving is ETA'd for May 2020(not jaanuary 2021)

i dont get it. moving it from POW to POS is still useless because it has been fully mined, ins't it ?
the coin circulation cannot increased anymore. mining bitcoin will never exist again.

Miners will still do the job and they will now mine to confirm transactions and they'll earn through the tx fees. Read these articles for better understanding.

Yes after 2140,there would be no more blocks to mine bitcoin and hence there would be no more rewards for miners for confirming transactions.At such a condition,transaction fee would be increased for miners as a compensation for the miners to keep the process ongoing.

[walemil]

I have been meaning to ask similar question since but I didn't let it bother me much because we will all be gone by then. All I know is that this will push up the price of Bitcoin due to scarcity. I also agree more with the fact that once the majority of bitcoins are mined, the sum of the transaction fees collected in a newly mined block would be enough to cover for the mining reward. It will be interesting to see more views on this.

[butka]

Yes after 2140,there would be no more blocks to mine bitcoin and hence there would be no more rewards for miners for confirming transactions.

In fact there will still be blocks to mine, because without new blocks there would be no possibility to record new transactions in the blockchain. However, there will be no reward in the form of coinbase transaction (the first transaction in the block included by the miner to collect the block reward). There will only be a reward as a sum of all transaction fees included in the newly mined block.

You are worrying much my friend. At least if all of the Bitcoin are mined then by the time that it happens then you are already rich.

Ye I can imagine it switching over to POS as an option but there is also an option to tip when a miner decides to mine a block. I can see this tipping implementation along with transaction fees as being sufficient enough to incentivise miners to secure the network

Will miners continue to mine bitcoin after that? Will mining still be profitable? Will miners used in mining evolve to consume less electricity and make mining profitable with fees in the future? How will miners survive with tx fees? I doubt miners will still do the job if these questions are still questioned 50 years from now. I also think that instead of earning through tx fees alone, there would be methods invented to make mining profitable again before all bitcoins are mined in 2140.

Less worried due to sleeping 6 feet under. Jokes aside, if bitcoin is to survive as global uncensorable cash by 2140, it will have to undergo transformations that might not seem realistic today. I get the feeling that today bitcoin is not treated with the respect it's due. The vibe I get from interacting with somewhat knowledgeable individuals on this matter is somewhat derogatory. They are viewing as an amateur product with lots of hype behind it. And to be honest, the petty politics plaguing the space are not helping.

Bitcoin will have to change into something user friendly, but professional. I don't know how else to put it, other than making a simple analogy: most people see bitcoin like a young skater with decent talent. Older folk tend to look down on him, cause they don't understand him. They don't think and honestly don't care if he ends up famous because of what he does. In order to appeal to this category of people, Bitcoin will have to be able to wear a suit and tie, at least from time to time.

[angelakrasnova]

The last bitcoin will be produced much earlier than expected, there are 4,000,000 bitcoins left, so that there will be changes in the coming years, but the consequences will be unclear
