Is the 21 milion of bitcoin a real limit?

[Bayoe_noe]

Good morning
Reading about bitcoin, I've found that there is a maximum of BTC that can be mined: 21 milions
It is said that this limit is due to the source code.

As probably you know more than I do about BTC:
- is it a real limit
- is it a good thing? I think it is but it looks like BTC will become more a commodity and not just a payment system

What do you think?

yes, it's true the total bitcoin is only 21M supply in the world, and the circulating supply is 16M until this year. maybe that's a good thing in terms of the price because it will make the price continue to rise, but I'm also curious what if one day the outstanding bitcoin has reached 21M. whether the price will be more expensive and what about the movement of bitcoin in the future....

[btcprospecter]

Bitcoin is nearly already more like a commodity than a currency more and more are holding instead of spending. The 21 million has already decreased and there is no way for sure to know how many have been lost forever. Once its all mined it all mined by that point we will more than likely have another coin that is the top contender.

[bloodyvio]

Yes, bitcoin is designed with max total supply 21M and it can not be added, unless the miners majority approves the design changes of bitcoin(fork).

In fact, Bitcoin has no limit, constantly creating forki this crypto currency, thereby uncontrolled emission of new coins, which is unclear on what depends.

I think fork will not affect the supply of Bitcoin.There's only one Bitcoin and only 21 million coins in that network because Bitcoin Forks such as Bitcoin Cash and Bitcoin Gold cannot be spent in the Bitcoin network

I think yes..21 millions is really the limit in supply of bitcoin this one reason why the value of bitcoin needs to be adjusted upward because the increasing demand needs to accomodate by the limited supply and I don't think any hardfork can increase the bitcoin supply they are just there to divert bitcoin market and offers so many alternative coins

[nesterpu]

As far as I know, the actual number of bitcoins that exist is only about 16 million bitcoin. Because there are a large number of lost users lost and irrecoverable. This makes bitcoin more scarce and more expensive.

Technically, there will always be enough for everybody because bitcoin is divisible. There could be smaller units than satoshis if the market deem it necessary.

[masterman]

Yes it is the limit, However, I think it could be possible that the limit could be increased after couple of years, although, it would be quite a challenge to do it.

[hualangktsld841]

Yes, the total amount is 21 million. This must be an important reason for the constant appreciation of bitcoin. If you can increase at will like a stock, then the bitcoin may have not existed, and it has already been devalued. If encrypted currencies continue to grow, I think some coins will slowly replace some functions of bitcoin. Some coins should circulate slowly and occupy a share in the encrypted money market.

It's a parameter in some code, so of course its not a real limit.

Yes, 21 million is the limit in which this was already estimated and unlock by all mathematician experts with no opposition on the figure but there is a good thing because this will be all mined after 127 years from now therefore we have lot of time to spend to be with bitcoin because no one will still alive after 127 years from now i think.

As per program it is the maximum number of coins that can be mine.
But as we all now it will be decreased due to the fact that there has already been a lot of coins that are either lost of forgoten forever.

[samarahewasht]

As i know 21 million is the real limit of bit coin.but we can not tell it's good or not for now because bitcoin accepting is just beginning.

The max supply of 21 million coins is true. It's a real limit, based on the fact that the reward which brings more units in circulation halves every 200.000 blocks. Starting with a block reward of 50 BTC, that means that the current block reward is 12,5 BTC which is true. Bitcoin halved two times, on 200.000 and 400.000 and is currently on 476.502. It's possible to calculate the limit using 50*0,5^n*200.000+x=x, increment n by one and doing the formula over and over till how precise you want the result to be, but in all cases it will come near 21 million.

In fact, there are only 21 million Bitcoins that can be mined in total. Once miners have unlocked this many Bitcoins, the planet's supply will essentially be tapped out, unless Bitcoin's protocol is changed to allow for a larger supply.

It's a parameter in some code, so of course its not a real limit.

What do you think about it? is it possible that this is a parameter of the code that it can be changed?...I didn't think about it, and now it seems to me an interesting thought

[Hasvak K]

Bitcoin is like gold in many ways. Like gold, Bitcoin cannot simply be created arbitrarily. Gold must be mined out of the ground, and Bitcoin must be mined via digital means. Linked to this process is the stipulation set forth by the founders of Bitcoin that, like gold, it has a limited and finite supply. In fact, there are only 21 million Bitcoins that can be mined in total. Once miners have unlocked this many Bitcoins, the planet's supply will essentially be tapped out, unless Bitcoin's protocol is changed to allow for a larger supply. Supporters of Bitcoin say that, like gold, the fixed supply of the currency means that banks are kept in check and not allowed to arbitrarily issue fiduciary media.

you can actually create gold arbitrarily in a particle accelerator. It is kust ridiculously expensive. But if gold someday gets expensive enough it may become viable.

[apolok]

yes,it’s true. 21million is a real limit. after mined 21 million bitcoin no more bitcoin will be mined.  and price will be sky rocket.Also you can google it,youtube it and can see in coinmarketcap.

[tatynka1204@gmail.com]

I think when 21 million is over, price will be in the sky )

What do you think about it? is it possible that this is a parameter of the code that it can be changed?

It could, but that would make Bitcoin a whole lot less appealing to the outside world in the way that you can't even trust on Bitcoin's technical aspects anymore. If one important aspect of this protocol gets changed, what prevents the same entities from changing things even further if they think it's necessary? It would basically mean the end of Bitcoin as being the most trustworthy coin in all sorts of aspects. That being said, I am glad there doesn't need to be anything done to increase the max number of coins to ever get minted. Bitcoin at some point may get so expensive, that the majority of the people won't even be able to afford 1/10th of a whole Bitcoin anymore. Bitcoin is extremely divisible by nature, and at some point we will not work with the BTC nomination anymore, but with mBTC or Bits.

1BTC = 1000mBTC (likely to become the default nomination)
1BTC = 1,000,000Bits
1BTC = 100,000,000Sats
