I see an underlying assumption here that I don't agree with: that tomorrow everyone will be using Bitcoin, so let's see how much it would cost if we split it evenly. I believe that in the future the majority use will continue to be, as it is today, as an investment, as an enhanced digital gold. And, since not everyone has investments and not everyone has gold, I think the same thing will happen with Bitcoin. In addition, as with everything, there will be people who will own and others who will own less, as happens now.

Anyway, thank you for sharing, but I really don't understand the message from it.

And the world number is not fixed, I don't remember exactly, but I can search somewhere on the web, about when bitcoin launched, how many people there are in the world, and the present, the future.

So this calculation doesn't make much sense to me, because I also know about decentralization but most of the bitcoins are kept in the pockets of whales so there's no need to think about everyone getting an equal share bitcoin.

here is a better thought experiment for you. to then use as a primer to then engineer a better "how many bitcoin per person" scenario

everyone thinks USdollar is the world leading currency of the world
but how many people of the world actually use and hoard USdollar

its not 8billion
its not 800m
its more like 400m (majority are just the americans 335m)

so dont use a 'if everyone had bitcoin how many sats would they equally get if shared equally'..
but instead assume a 5% of population (400m of 8billion pop)

so lets use 400m as a fair number.. (seeing as if you add up the published revelations of user accounts totals on exchanges is nearly getting to that number already)

19.4m  btc 400m pop = 0.0485btc per person as a reasonable hoard per population
if you own more then this 0.0485btc level of btc. consider yourself ahead of the game (better than the average)

I like that metric. If you do the total supply (21 mil btc or 2.1 quadrillion sats) divided by current pop (8.25 b) you get about 0.0025 btc or 250,000 sats, currently.

We should have some sort of unit of measuring bitcoin in which one unit is btc/population. So currently ~234,573 sats would be equal to one "bitcoin-person" or something haha. Then people could measure how much bitcoin they have against this metric of BTC per human.





I have barely bought bitcoin since 2019 cuz I retired off my bitcoin in 2019 and so no longer earn an income from working, but I do trade crypto during the bullish years of the market cycle so I do make some income... I think I might try to start to DCA either weekly according to this supply divided by global population metric - 250,000 sats each time, close to one bitcoin-person unit. Weekly would allow me to accumulate 0.13 btc per year which ain't bad. Thanks for the inspiration OP!

In fact, I just now started! Picked up my first new bitcoin-person (250,000 sats) at $68,900 just a few seconds ago. 

It's a simple website indeed, but I don't know the purpose or relevance of it. Anybody can quickly compute it for himself/herself if he/she wants to know the numbers. I guess a website solely for such purpose is a bit superfluous.

Anyway, there might not come a time in the next century or two when every single person in the world owns Bitcoin, unless perhaps if Bitcoin becomes the legal tender in every country all over the world.

But the point is that there's always a Satoshi for everybody who's interested.

Yeah obviously its kinda arbitrary, because its not like everyone in the world is ever going to own Bitcoin. And meanwhile there are a lot of non-person entities that are going to own a ton of bitcoin, replacing billions of people, like corporations, govts, investment firms, etc.

Realistically we might say in the next 20-30 years maybe there will be another billion people who enter bitcoin and they are going to be competing to buy only a few million bitcoin.


But for simplicity this is nice. Its meaning is just that if you get above this small amount of Sats you are already above what the average could own if everyone owned bitcoin equally. So if you get multiples of that number you can think of yourself as taking up more and more 'people' out of the population who could own Bitcoin, and therefore you are getting more and more of an advantage on the average person when it comes to this extremely scarce and extremely valuable asset. And right now its a small enough value that at least for people in richer countries it could be a good first buy-in for anyone wanting to tip toe in into the market. And it's nice to think something along the lines of:  "oh Bitcoin is so scarce and I was lucky enough to get in fairly early so I already have 100 (or however many) people worth of bitcoin!" And with how valuable a whole bitcoin is these days, its kinda of a nice usable unit of measurement for bitcoin. A Sat is worth basically nothing, and hardly anyone who hasn't yet started buying Bitcoin will ever be able to get a whole bitcoin, but there are hundreds of millions of people in the world who don't own bitcoin yet who could easily buy this amount of bitcoin.

I know about assumptions with figures on that website. Many assumptions are there like the world population is not dynamic and real time update, it probably is updated regularly, not real time. Oppositely Bitcoin price is updated real time.

A big assumption is all people on the world will invest in Bitcoin, to make this calculated figure. This will never happen but this big assumption and the calculations give us a raw view on what will happen for each person if all world people will spend money to buy bitcoin.

Fortunately, because many people have yet invested in Bitcoin, we are early birds and can take advantage of it and accumulate Bitcoin with cheaper price than when more people will join this market.

I think the calculation is just trying to show how much bitcoin is out there in ratio of all the people in world. I, myself, also do not understand what the point of the calculation is. This is all the population in the world but we are all not equal in a sense that some would be closer to retirement while someone could have just been born. How can someone who had just been born have their own money? They won’t even have any need for it let alone knowledge on how to actually use it.

A simple website, but its idea is really fun. Although it is not practical in reality due to many of the reasons mentioned by the members above, it is still a funny and entertaining idea, even if it is hypothetical.

The site calculates the number of people and divides the number of satoshis by the entire population regardless of anything else, but this is not true because newborns cannot own Bitcoin. In addition, there is a large number of people who have not heard of Bitcoin yet, and some of them have heard but do not have the money or do not know how to use Bitcoin.

The site calculates the percentage of large increases in the number of people in the world every second, but in return, it also does not calculate the percentage of large deaths that occur every second, and this will lead to an error in the calculations.

Therefore, this remains just a theoretical study and can never be applied in reality.

What I've noticed is that the decimal for satoshi per person is dropping in seconds and the same goes for the world population and moving a lot increasingly per second. While with my simple research, there are 4.4 people that are born every second. The website tells more than that based on its move per second. Anyway, that's not the important point but if there's a basis and API with this metric that the owner of this website did, it's actually a good information and it just made me remember the websites like preev.com that I've missed already although it tackles differently as it's more of the price of BTC only and some other altcoins.
