Hmmph.... seeing two different stats for the current # of bitcoins mined:

1. Coinmarketcap says there are 14,989,075 in circulation at the moment.

2. Blockchain.info says there are 14,992,450.

Anyone have a handle on which is right? Or what the truth is if neither?

The reason I found this bit of trivia interesting is that a few weeks ago it looked like Bitcoin might hit the 15,000,000 mark right on Christmas day. Now it looks like it will beat that slightly. Still, Merry Christmas, Bitcoin - and bitcoiners everywhere. :-)
two sources above are very trustworthy, I also think that was correct data, many people proclaim that indeed bitcoin leaving 6 million units again, but if you want to be sure, just wait until the time bitcoin bitcoin halving or can no longer mine Grin

I don't really believe either number is possible but time will tell.

I don't get what is exacly the point on knowing the accurate number of btc in circulation... could anyone tell me?

Also, does this calculations account for cold strored coins?

I haven't done the calculations yet but I remember reading earlier this week that the magic number may happen in the magic day (x-mas) so 25 of December.

I created a similar topic when BTC broke the 14,000,000 mark... Can't wait for the next halving. It's quite shocking to see BTC's creation still so fast when the 21,000,000 limit is more than 120 years away.

I expect a substantial price decrease after the mark is passed.

Interesting... didn't realize how complex this would be when I mentioned it here. So if some early blocks had no bitcoins associated with them, does that mean the final total supply mined is not "21 million" like everyone says, but something slightly different? Or will there end up being extra blocks mined in the end to reach 21 million despite that early bug?

I just brought this up as trivia, not for any grandiose purpose. Am glad to be learning something though, and I'm sure other readers are as well.

the bitcoin protocol maths is that 15mill will hit at 390000.

but there were bugs, there is the genesis block thats unspendable and other reasons why there wont be exactly 15mill coins in public circulation at 390,000. some are even lost due to human error (destroying their hard drive) the argument about bugs, errors and human caused loss can make any math pattern or code rule inaccurate. but i prefer to stick with the rules of bitcoins. so block 390,000 with14,997,000~ coins in real circulation is as close to an accurate rule abiding bitcoin block to pay homage to.

as for the year 2140 it wont be exactly 21,000,000 coins. as the reward halving maths doesnt become that exact. but we dont know if someone will change the protocol in 100 years to make the total coins a more precise, exact 21mill amount.. and because its not a worry for 100 years, regarding far less than 0.02% of coins.. i dont think you need to worry about such things right now

There were never going to be 21 million bitcoins mined.  People that say that either misunderstood what they heard or heard it from someone else that didn't know better.

The initial theoretical maximum number of bitcoins that were going to be created was:
20999999.9769

It's just easier to say "There will never be more than 21 million", or "The number of bitcoins will never exceed 21 million", or perhaps even "There is a limit of 21 million" (all of which are true), than to say "Bitcoin was designed with an intention to mine twenty million, nine hundred ninty-nine thousand nine hundred ninty-nine and nine thousand seven hundred sixty-nine ten-thousandths bitcoins".

Or will there end up being extra blocks mined in the end to reach 21 million despite that early bug?

Nope.  No extra blocks.  The bitcoins that weren't mined simply won't exist.  The total that will be paid out as block subsidy will just be that much less than 20999999.9769.

block height 390,000 is the magic 15mill coins mined in circulation number you are looking for

current block height 389566
=210,000 at 50 coin = 10.5mill
=179566 at 25 coin = 4.489150mill

=14989150 -15mill =10850 coins left = 434 blocks = ~under 3 days left

Of course there were some early blocks that were mined by someone that had a bug in their software.  Therefore, they created blocks that were missing bitcoins.  Those bitcoins were therefore never mined, and never will be.

So, you'll have to define what you mean by 15,000,000 BTC mined.  Would you consider those missing bitcoins to be "mined" but instantaneously "lost", or since they were never available as a block reward at all, would you consider them not to be mined?

Then if you're looking at bitcoins "in circulation", you may also want to consider that there are more than 2,500 BTC that are provably un-spendable.  These bitcoins have been effectively permanently removed from circulation.  https://bitcointalksearch.org/topic/how-many-bitcoins-have-been-provably-lost-at-least-675321

I personally trust blockchain more, so i'm going to go with them. The 15,000,000th bitcoin will come into existence two to three days from now.

Do you guys think this one bitcoin, whoever mines it, will be worth more than other coins? It's a "fresh" coin too.

Well, there are created around 3600 Bitcoins a day. So, it seems that Coinmarketcap.com is around one day back.
Why is it so important for you to get the exactly number?

maybe the OP wants to send a Tx with a message at the right time, with a fee to ensure its added to block 390000, to hold it in posterity. for whatever reason he wants..

but thats just my wild guess

I've actually never looked at the supply that closely. After doing some research now, it does seem like a lot of sources show a different number. OP you could manually calculate it, it might take some time to get the right number though.


Update: There you have it.
