Bitcoin Forum

   There are lots of resources at www.It requieres time and professionality.I was aware of many data resources but thanks to the forum members I have reached many.

    However I would like to know if to know if there are any resources for the parameters below.

1) How many btc wallets have been activated and how many of them are actively used?

2) What is the emission of btc?Here I want to know if there are parked btc, or forgotten wallets.

3) What would be the fair prize for the one who gives the answer?

I will edit this topic whenever I have unanswered questions.If you have unanswered questions we can also add the list.

1. No one knows, no way to know.

2. Not exactly sure what you mean by "emission of btc" and "parked" btc, but there are forgotten/lost btc.

3. Answer to your questions? I dunno, you decide.

Like steven0021 says, there's no way to know if the private key for a certain address is forgotten, or if the address is just dormant.
There are some statistics about the number of addresses containing inputs. You can generate your own statistics by using tools like https://github.com/znort987/blockparser or import the full blockchain into a mysql database using ABE (requires weeks of your time and a sufficiently sized server). If you import the full blockchain into a mysql database, you could easily query how many addresses generated outputs or got imputs over the last x weeks.
By the way: 1 wallet usually contains dozens of addresses. An address that hasn't been used in years might still be part of an active wallet.

12.5BTC approximately every 10 minutes untill the next halving. I'm pretty sure a lot of people are hodling and lots of private keys have been forgotten over the years... The ratio between the two is impossible to figure out

Nothing... since there is no right answer here.

Term emission of coin means premined , mined and will be mined number of coins.For example for BTC the number is defined as 25 M.

The aim of these questions is simple, to measure the interest of people to a defined coin or altcoin.If we can not measure it by active and abondoned wallet number, perhaps we can test it how many people has positions at it on a defined exchange (ex. poloniex).

I also heard a lot about parked (never sold or bought) coins.Here I use 'parked' for mined and being left.Perhaps there are 2 M coins of that kind.

I want to reach resources.I want to reach database of exchanges (how many customers have position at a coin, coin number per investor, etc.).I believe they are announced at somewhere which is open to public interest.

A total of 21M bitcoins will be mined, and 15M~ have been mined. No coins were premined (coins mined before public announcement).
Some other people that screams bitcoin were premined have their own definition of premine.



There might be more than 2M, but the thing is we can't really be sure if a btc is parked or not. And no, exchange database are generally kept private.

1. No one knows of it because the only knows the address is the owner of bitcoin wallet.

2. there must be, I have to leave at a bitcoin on the wallet because I forgot my password.

3. only you know what is a fair prize for it.

Emission - the release into circulation of new money, which leads to an increase in the total money supply in circulation.Emission of bitcoins is carried out not by some request of the system owner. Bitcoin is impossible to counterfeit or "turn on machine" – this currency is mined in real money simply number. Engaged in production of so-called "miners" — it can be as individuals and organizations that purchase and maintain computer hardware that produces bitcoins. Their equipment every second is engaged in solving mathematical problems, in which is generated the currency. This same equipment is used for the operation and security of all network as a whole.

you are comparing bitcoin to a crappy pump and dump altcoin.
first of all there will be a total of 21 Million coins in the end and no coins were "premined'. because premine means the creator generates coins before the blockchain of the coin is even released. but bitcoin was released and from coin number 1 was mined publicly.

New information I got in this thread bros. I was not know emission of bitcoin or parked bitcoin. Thanks for the information.
