when will all btc be mined?

[btcfre@k]

I know this question have been answered before but still i would like to know with all the new investor in big mining central,i would like to know if we will reach the mining final sooner than the early calculation estimated.

guys keep it simple,smile and cheese

The estimate is 2140 based on the block reward halving frequency of four years.

[ebliever]

The intensity of mining (hashrate) has (virtually) no impact on the rate at which bitcoins are mined. BTC are currently mined at 25 BTC every 10 minutes, the reward halving every 4 years (next in 2016). I believe this runs until ~2140 AD.

Well That's a really long long time , we would be all dead by then Let's hope that Bitcoin will live

actually,all bitcoin will be mined soon

[DannyHamilton]

Interestingly, it will take more than 30 years to mine "the last" bitcoin.

The 20,999,998.9769th bitcoin will be mined at block 5121610 somewhere around the year 2106.
The last block reward will mine the 20,999,999.9769th and will occur in block 6930000 somewhere around the year 2140.

That means it will take nearly 34 years to mine that last full bitcoin.

it is an incredible thing,while today we have 25 new bitcoins every 10 minutes  
we hope bitcoin is more valuable in that days

yep, get em while they's cheap.

+1 there is a long road yet for BTC, ppl should understand it and start to care about invest on it...

lol i was thinking arround 2040, 2140 is just awesome...

Until quantum mining is perfected, difficulty should be able to adjust for network hashrate increases.

It will be more valuable. 90% of the Bitcoin will be mined before 2070, someone can calculate a precise year?

[hyphymikey]

I thought it was 2138 or 2139 since it is suppose to take 140 years from jan 2009

[exoton]

The intensity of mining (hashrate) has (virtually) no impact on the rate at which bitcoins are mined. BTC are currently mined at 25 BTC every 10 minutes, the reward halving every 4 years (next in 2016). I believe this runs until ~2140 AD.

This is not true. The network difficulty is reset every 2016 blocks so that if the hashrate that was being used the previous 2016 blocks continues to be used (and the same level of luck is realized) then the next 2016 blocks will take exactly two weeks to be mined.

Every time the difficulty rises, it means that the previous 2016 blocks took less time then 'expected' to be found.

It is really not possible to know with any kind of certainty when the last block with a block subsidy will be mined as this is largely dependent on the difficulty between now and then

Another answer may be "never".

If bitcoin price rises over time, the number of decimal places may extend to accommodate smaller payments.  Each such extension increases the time before the block reward halving will round down to 0.0000......0

This can be a natural consequence of "lost or destroyed" coins, which increase the scarcity of existing coin and thus also perhaps the price of them.  So this can in principle continue for so long as there are people exchanging bitcoin with one another. 

[cyberpinoy]

if nothing drastic is canged in the Protocol then NO it will still be (I think it is) 2040 and only 21 million mined. that was how it was set up.

[bornil267645]

Bitcoin mining is loosing it's popularity recently... So it might take some time...

[dsly]

Its impossible to know this, as the difficulty increases, miners might go away, so it could be anytime within the next 100-200 years.
Expected is 2150 though/.

Moving the decimal does not change the number of existing bitcoin, only the divisibility of them.  A transaction (like a couple pizzas) that was once 10000 bitcoin could now be .01 bitcoins.  If by 2140 a couple pizzas is 0.00000000001 bitcoins, there will be no way to order them unless the we go to more decimals.  It isn't a very drastic change after all, and very possibly necessary.

If 50 -> 25 -> 12.5 -> 6.25 -> 3.125 -> 1.5625  -> 0.78125 takes 24 years, or about a generation with halving every 4 years, then if the number of significant digits increases by 4 faster than every 50 years...  it could be forever until there are no more block rewards at all and that last bitcoin is never completely mined.

That doesn't change anything : wikipedia bitcoin mining

[Totscha]

Let's keep things in perspective. In 10 years 95% of bitcoins will be mined. The rest will be spare change and less and less relevant to miners for the next 100 years.

Transaction fees will be the main incentive for miners.
