I claim the OP is currently wrong. I don't believe there are 2 million Bitcoin users at this time.
How can you possible know the number of people in any category since lots of people can easily have more than 1 wallet?
That is why the thread is so long because we do research, not just copypaste numbers.
I have re-read the entire thread and collected all the relevant comments as follows.
edit: Ah, as I was writing, I remembered that average remaining investment was calculated with bitcoin price of $100 instead of the current $200. This makes the total number of bitcoin users 350,000, which I think is very realistic considering other metrics.
This was the figure I heard last year and seems to be more realistic when you factor in my analysis below.
They also didn't take into account that wealthy bitcoin owners break up their wealth among many smaller accounts, and they linked a bunch of addresses together with the assumption that if one address sends money to another, both belong to the same person, despite the transaction possibly being between two people.
All wallets are in a sense personal wallets. Wallets that exchanges use "belong" to the exchange and the exchange owes users BTC upon demand that they might pay or not. So those wallets are more concentrated and large owners wallets are more distributed. Perhaps it averages out. I don't think bitcoin will somehow negate the laws of human interaction. BTC will flow from incompetent users to competent ones so concentration much like with other wealth is unavoidable.
I invalidate the above by noting at least Coinbase, Blockinfo, and Localbitcoins allow users to create multiple (unlimited) new receive addresses with the click of a button.
- My gut feeling is that number of bitcoin holders was estimated a little too small last time - an analysis of Bitcoin client and wallet software userbases, (Rassah!
) plus Coinbase users, Bittiraha.fi users and Localbitcoins activity, and new user count in exchanges, is what we need to find more reliable figures.
In Japan, 週刊新潮 (
Shukan Shincho, a weekly news magazine/tabloid) published a section on Bitcoin this week featuring an interview with a MtGox rep. The rep said that they have 720,000 users, of which 400,000 are active/frequent, and that 20% of their users are Chinese, up from 4% in April.
OK. I think for Mt.Gox, the "active" number
400,000 is what we should use. The total number possibly includes also accounts that have not been funded + the ones that have been emptied (and abandoned). The ratio of "active":"total" is about the same as in Silvervault.
Then we know that Localbitcoins has
120,000 accounts, with a growth rate of 2.5% per day. If you just buy from any of the merchants, you do not need to register afaik, so the total number of users could be larger. On the other hand, LB has quite many accounts with zero trades, since it has grown so rapidly. Perhaps 80,000 users would be a good estimate.
Coinbase has
488,000 customer wallets. The number is probably "total", in which case about 300,000 would have a balance.
BTC China has to have quite many accounts, but I did not find the information publicly. Help!
Bitstamp ditto!
Number of Bitcoin clients downloaded is
4,350,000 over 5 years. How many of these is in use?
MyWallets (blockchain.info wallet) walletcount is
690,000.
Bitcoin network has used
11,462,000 addresses, of which
600,000 (exact) have non-dust (>1m
BTC) balance.
Then there are other exchanges and wallet services, which you can add if you find nice figures.
In my understanding, the Bitcoin ledger (address usage and balance distribution), currently sets the upper limit for bitcoin number of users. Especially considering that 1m
BTC only 2 months ago was only $0.13 or so, most of these accounts are not the sole acconts of bitcoin holders. On the other hand, most of the larger accounts
We need to evaluate, how many users should be added who only use exchanges for storing their bitcoins. This increases the total number.
On the other hand, there is a huge overlap in the numbers, since I alone have 8 accounts in the abovementioned sites only + several addresses with balance in the ledger.
Now, please try to keep this on-topic so that we get the december figures out. My experience from the software download industry is only about 5% of downloads become users, due to repeat downloads for same user, failed downloads (but recorded as downloaded), curiosity only, etc. So 4.4 million x 0.05 = 220,000. The rate might be a little higher since Bitcoin is a very serious tool.
I created a few localbitcoin wallets and I am not even serious about Bitcoin (possession of less than 5 BTC which isn't even mine). You note the overlap in your case too. How can a wallet receive external Bitcoin sends if the wallet does not have an address that has been used? So obviously given the 600,000 non-dust address, then many of those online wallets have never received any Bitcoin sends, and were I guess loaded with fiat exchange. Do we even know how many have 0 balances, i.e. were created but never funded? When Mt.Gox says 400,000 active, does active mean has a balance or user has signed in recently (I will assume the later since companies have an incentive to pump up their importance)?
Given all the major online (potentially off-coin) services mentioned add up to maybe 2+ million with some unknown divisor > 1 and < 10 and the number of non-dust on-chain addresses are 600,000, it seems the
true number of users is still less than 1 million.
It seems reasonable when factoring in several billion people in underdeveloped countries which have no use for Bitcoin yet, nor are investors, that only 1 in 10,000 of all people on earth are Bitcoin users, i.e. 7 billion divided by 10,000 = 700,000 users.
By user I assume we mean someone holding a balance denominated in BTC which they have not abandoned and long since forgotten about. This an important distinction, because then we can
eliminate all addresses with less than 0.01 BTC from the count of users at the current price < $1000 per BTC.
also i think the number of people who hold .1 of a btc or whatever is not many. if someone is going to get into btc only a few people are going to stop at .1 btw or less.
So I would estimate the current number of bitcoin users at 1,500,000 at the bare minimum, and more likely closer to 2.9 to 3.25 mil.
That was also my original estimate, but it is unrealistic because then most of the accounts would need to be too small to be bothered.
None who reads this has a small bitcoin balance, but do you even know of people who have, say, less than
BTC1?
I knew at least 4 who have just
BTC1. Some of them wanted to see what it was and just bought
BTC1 to play around with, others got
BTC1 on a paper wallet as a gift and still have it. Not sure about those who have less than 1
BTC. I suspect there may be a few newbies with that amount, if they were only comfortable putting about $100 into it to start.
After delving into this matter in the last 1-2 days, I am tempted to drastically reduce the total number of bitcoin users, because I haven't found the mechanism that actually would have produced millions of sub-BTC1 holders so far. The number of investors will likely stay quite much the same after the update.
It looks from this like several million will be the correct figure.
I heard that only about 3 million bitcoin addresses are used. I would say that the number of addresses > number of users.
Myself, I have used dozens of addresses, and don't consider to be a heavy user of addresses.
