If Bitcoin had a Billion Max supply instead of 21 million....

[very_452001]

Then how much you think the price of 1 btc be today? Is it just doing some simple math to work out the price or is it more to it?

If 1/8th of the world population had 1 btc each then what you guys think the price will be?

There's a 1000 million in 1 billion.

So essentially 5 50 times more Bitcoin, off the cuff response - it would still be limited supply!
The same reward structure would remain I guess so it would take
longer to mine 1,000,000,000.

What is appealing to investors at the moment is the fact that Bitcoin is a deflationary
asset compared to FIAT which is inflationary, Gold is the closest to Bitcoin but still is
or isnt limited [thats a different discussion] and is controlled.

If Satoshi had set the limit at 1Billion I dont think it would make a difference to the
way we think or the appeal of Bitcoin,

On the other hand if there was a consensus to change the limit from 21Million to 1Billion,
Well thats a different matter.

Marketcap = Price x Current btc supply in circulation

Price =             Marketcap
             Current btc supply in circulation

Bitcoin with 21 million max supply and currently 18.6 btc in current supply, marketcap recently will be:

Marketcap = 33000 x 18.6 million = $614 billion

But, if assumed the supply is 21 billion which means assuming 18.6 billion has been mined into circualtion already.

Then, Price=      614 billion
                                18.6 billion
                                    = $33

Bitcoin at $33000 with the current supply at 18.6 million will have a price of $33 if the current supply is at 18.6 billion if having max supply of 21 billion.

That is just an estimate which can make you to understand how increasing supply can reduce price, the value is not exactly accurate. Some coins with low price and too much supply can be burned in order to increase the price.

[joniboini]

Well, who knows. The dynamics would be different and the interest from others might be lower than you might think. It might worthless too.

Instead of asking about the supply, I think other questions such as what if Bitcoin uses PoS, or what if the block rewards continue to exist at 0.25 per block (or other random numbers) would be more interesting than guessing about the price of a single Bitcoin.

some coins with low price and too much supply can be burned in order to increase the price.

Keep in mind that this is just a strategy, but not a guarantee that demand will change. It might increase the price for a while and then get dumped without any recovery.

[Lucius]

There is a big difference between 21 million and 1 billion, here we are talking about a difference in max supply of almost 50 times. If Satoshi had set things up that way to be 1 billion BTC and left all the parameters the same, today we would have a little less than 900 million BTC in circulation, and you don't need to be any mathematical genius to understand how much that would affect the price.

It’s hard to say how much 1 BTC would be worth in that case, maybe a few hundred dollars or maybe a few dozen? What is certain is that Satoshi did not do anything by accident, but thought of everything very well before the whole thing became public.

[DeathAngel]

All I can say is thankfully bitcoin has a capped supply. Most of the coins with close to infinite supply are trash. Bitcoin is scarce & that’s one of the main things that makes it so valuable.

[Charles-Tim]

Keep in mind that this is just a strategy, but not a guarantee that demand will change. It might increase the price for a while and then get dumped without any recovery.

You are correct, not only supply that determines the price of a coin, also demand is another main factor that determine the price of a coin. Also, we should have in mind that nothing will alter the supply of bitcoin instead will only result to a hardfork while bitcoin remain bitcoin with max supply of 21 million btc. All the calculations is just based on assumption of what the price of bitcoin will be if the max supply is 21 billion and yet having such demand and the likes that happened to bitcoin normally. It is just an assumption, just for the OP to understand how increase demand can reduce the price of a coin while others factors remain constant in the calculation which makes it not accurate.

[yazher]

As simple as the total supply of the other Altcoins out there where they only get low prices because of their massive supplies and most of the time to resolve that issue they burn some tokens just to increase the price a little bit. Well, if bitcoin had such massive supplies I think the price will remain the same but we will trade more BTC in the market and most of the preferred to invest in because of its popularity and decentralized coin. Those investors prefered this kind of coins because they are simply anonymous and no SEC or whatsoever can manipulate the price if they do their so-called investigations.

[NeuroticFish]

Then how much you think the price of 1 btc be today?

The simple answer is that it's impossible to know. If this would be different, you don't know what else would have been different or somewhat affected by this difference, like the psychological factor for buying or selling Bitcoin.
I think that it's impossible to quantify what would be the price now. Imho it's not just simple math.

[davis196]

The total supply doesn't matter for the price.What matters is the mining difficulty+supply and demand.
If the mining difficulty remains the same,the total Bitcoin supply can be even 100 billion BTC,but it would still be that hard and expensive to mine Bitcoins,therefore the total BTC supply might never be reached.
If the total supply is 1 billion BTC,and the mining difficulty gets reduced significantly,then the BTC market will be flooded with newly mined Bitcoins and the Bitcoin price will go down,if the demand for BTC remains the same.
The Bitcoin price is all about supply,demand and mining costs.The total BTC supply doesn't matter.

[Jawhead999]

1000 million : 21 million = 47,61 ratio

Current price = $33,460.37

Bitcoin price with 1 billion max supply = $33,460.37 / 47,61 = $702.80

It's just a simple math where the demand is same right now with 18,609,881 BTC circulation supply, the fact is we can't know how's the demand when Bitcoin only in that's circulation with 1 billion max supply, I think many people don't have high demand of it since the circulation is very little than the max supply.

[tranthidung]

To say about total supply and price, you guys forgot about one decisive factor:

• How long will the total supply be released/ mined/ staked/ minted (not only for bitcoin)?

It is a decisive factor because the more years, decades from now, the higher population over the world so it will be the same story for bitcoin scarcity if the total population increases and reaches to the same rates of the increasing change in the new total supply.

With a bit less than 21 million bitcoin, it will be mined all as schedule in the year 2140. So with 1 billion, what if it will be mined all in the year of 7854 (5714 more years than 2140). I bet that the world population will rise more than 47.62 times (1 billion / 21 million = 47.62). It will do rise exponentially. Of course if the Earth will survive up to that year.

[RondoAnyar]

The falling price of bitcoin will definitely happen and bitcoin is not one of the best coins at the moment. I think a coin that has a very large total supply only ends up being sampaj because it can't pump its very high prices. so bitcoin is currently in a good position because of limited supply and is in demand by many people

[bassbity]

in fact, that's enough for bitcoin with a supply of 21 million. nothing less and nothing more. limited, rare and may not be allowed to be recycled or more precisely refurbished if it is used up. then with 21 million, the price will continue to rotate, and it will probably go down as time goes by and the owner dies.

[thecodebear]

Nothing would change. The market cap would be the same, and the price would just be lower by the factor of expansion: 21 mil / 1 bil = 0.021 * ~$33k = ~$693.

So price would be around $700 right now.

This is of course assuming everything else stayed the same in relation, so the initial mining reward would have been 50 BTC * (1 bil / 21 mil) and we'd still have nearly all of the supply mined at this point and mining would finish around 2140.

There might be some small psychological difference but probably not. 21 million coins is still a ton of coins, I don't think there'd be much of a psychological impact on the idea of scarcity if there were 1 billion, as both 21 million and 1 billion are very high numbers. If it was a difference of a low number like 1000 BTC supply cap versus 21 million BTC supply cap (and assuming the number of satoshis in one bitcoin was adjusted up so that there would still be roughly the same amount of satoshi's in the supply cap for purposes of transactions to have the ability to be extremely granular) that might have a psychological impact of making the supply seem even more scarce. But in general the scarcity model of Bitcoin has nothing to do with the actual number of Bitcoins available, it has to do with the halving which makes newly minted Bitcoin dwindle over time and the fact that there is a supply cap in the first place.

[serjent05]

With this kind of situation, all we have are theories and assumptions.  All the computation will have a huge error since we will never know what will be the market condition if Bitcoin has a Billion supply.  The given calculation on the earlier reply would give us a hint but it is also possible that there will be no change in prices.  People are sure to know how to complicate things with their wide imagination.  Why not just enjoy the volatility of Bitcoin and take profit from it  . 

[20kevin20]

Honestly, I think it'd be just the current price divided by 47.619.. So around $700 today. I don't think the supply matters as much as the tech does, especially since Bitcoin would've then had 1B max supply since inception. It's like we'd think what 1 BTC would be worth if there were only 441k BTC max. The effect is imo the same.

This is correct where no matter you do changed up the supply if the demand would really be still the same then it would really be showing off the same effect.
It may be on different numbers but it wont really change a thing and also that not all coins had been mined though so calculations are presumptions.
We dont need for the entire supply to increase because the entire population can still able to own coins with fractions.

Marketcap = Price x Current btc supply in circulation

Price =             Marketcap
             Current btc supply in circulation

Bitcoin with 21 million max supply and currently 18.6 btc in current supply, marketcap recently will be:

Marketcap = 33000 x 18.6 million = $614 billion

But, if assumed the supply is 21 billion which means assuming 18.6 billion has been mined into circualtion already.

Then, Price=      614 billion
                                18.6 billion
                                    = $33

Bitcoin at $33000 with the current supply at 18.6 million will have a price of $33 if the current supply is at 18.6 billion if having max supply of 21 billion.

That is just an estimate which can make you to understand how increasing supply can reduce price, the value is not exactly accurate. Some coins with low price and too much supply can be burned in order to increase the price.

Lets look at a popular Altcoin right now that is Chainklink LINK.

Its price now is $24 and a max supply of 1 billion.

So if Chainlink were to pass $33 price today then as of today then you are saying Chainlink is better than Bitcoin for example?

[hatshepsut93]

I think the marketcap would be lower than the current one, because a billion of coins would be perceived as less scarce than the current max supply, even if in both cases the supply is limited. On the other hand, having lower total supply could also have negative effects, if it was too scarce, like let's say 10,000 bitcoins, it would be viewed more as a collectible rather than a currency or a store of value.
