Right now bitcoin has 8 decimals but if the protocol is changed for it to have 16 decimals or more it will take more time to reach the limit...

No... No. No... No.. No! ... No!
I mean, you are right that Bitcoin may introduce additional decimal places, but they wouldn't devaluate the currency. 1 BTC would still be 1 BTC you would only be able to divide them further. It would have nothing to do with the block reward, which still would be phased out after 21m coins!

Extending mining to sub-satoshi block rewards wouldn't result in more than 21 million BTC due to the constant halving. However, I don't believe that there would be sub-satoshi block rewards anyway.

Wow I wonder how society will be when Bitcoin mining is over  Embarrassed

Mining doesn't stop when the block reward reaches 0.

When will the bitcoin block reward be halved from 25BTC?

every 4 years beginning from 2009
2013=50 to 25coin,
2017=25 to 12.5coin
2021=12.5 to 6.25coin and so on

With the increasing difficulty, we have found blocks faster than the 10 minutes mark on average, and so we will see next block reward (the 420,000 th block) in 2016. http://bitcoinclock.com/

any idea when will bitcoin reach 21 million mark as their are currently 15 million coins.

Are you sure there are 15 million coins already? Coinmarketcap.com says that there are a little over 13 million coins.

You are right.
You can check the total number of mined bitcoin on https://btc.blockr.io/trivia/blockchain and https://blockexplorer.com/q/totalbc

Even though, we will reach 20 million before 2030. That is 95% of the theoretical limit.

Just a thought: All miners can collectively game the system so the 21 million mined coins can be achieved much quicker. Right before difficulty change, majority of the miners drop out so that the total network hash power plummets, so after the new difficulty correction drops, all miners jump back in. This would result in blocks being much faster than 10 minute averages. After 2 weeks, miners drop out again until difficulty change, then jump back in. Rise and repeat. Cutting down the 10 minute block times in effect would cut down the number of years required to mine out all blocks.

Practically speaking, this won't ever happen, but it's still a possibility.

Are you fcking retard?

Difficulty adjustment is based on number of blocks not "2 weeks"

When all the miners drop out, says good bye to your "10 minute" block time along with your stupid "2 weeks".

For a hero member to say such stupid fck, i think its safe to assume you're a fraudster/scammer. (hint for noobs: there are ppl who sell hero member account)



Holy shit, did you really just this this aggressive from a post?

OK, I had a brain fart and mixed up the average 10 minute block time and 2 week difficulty adjustment. I also I made the wrong assumption that difficulty was calculated based on the very last block before difficulty adjustment. Hence my reasoning of most miners dropping out at the very last minute, so that network hash power drops, so difficulty readjust according to how long it takes for the last block to get confirmed.

From your aggression, I think it's safe to assume you kill people IRL. seriouscoin, why so serious?

2) 2140. It won't be before then, unless the protocol changes.

The block reward schedule is based on blocks, not time. It is only indirectly related to time because a block is supposed to be produced every 10 minutes on average. However, if hashing power (and thus difficulty) increases, the average time is less than 10 minutes.

The first halving occurred about 2 months early. Assuming that the hashing power continues to increase, the last block reward will occurr long before 2140 (my estimate is around 2130).

Last full block reward that is.

Transaction fees will always be included in blocks, and so higher fees will become apparent over time.

Maybe it's good for the network, maybe not.

1) They're at just over 13 million. Not 15...
2) 2140. It won't be before then, unless the protocol changes.

That won't work. You don't understand how the difficulty is calculated. Anyway, the only way to speed up the block reward is to raise the difficulty.

Approx 140 years to reach the 21m mark I believe.

When the last bitcoin will be mined probably it will be the world currency and most of our future grandchildren will be rich.
But bitcoin could die and our efforts to gain some coins will be useless, who knows.

And as a side note, if a decimal place is ever added for some reason like a need for additional units, which I suspect is highly unlikely, every holder of btc would hold the exact same % of total coins before and after the addition.  This is unlike the current fiat system which issues new currency units in a completely uneven/unfair way.  No printing money and handing it to banks/companies bail out style.
