I had given someone 100 BTC for medicinal supply, they sold it and returned 25 BTC profit.

I agree, but I can respect that certain individuals might want discretion when it comes to their business.
I have all the documentation I need, all chat histories recorded.
If there were ever any disputes, I am prepared to handle it on my own.
The public forum would not be of much help to me.

Just to update you guys, I am in and out of the office all day. I am also post limited.
The Document Verification, is digital image.
I only request this to hold some sort of evidence that you are who you say you are.
The only way to get out of sending me a digital copy, is to meet me in person.

I have taken a lot of loans into consideration, and I think I have found my bitcoins a new home.
I have taken a shot in the dark and agreed to send some of you my coin.
If you are ok with the transaction being public, feel free to post it here.
If you wish to remain private, that is fine. These eyeballs dont have to see your business.

Firstly, I would not loan 25 BTC to one user. I am thinking maybe 5 maximum per person (maybe 10 if you have actual reasons).
I am assuming this post was a joke? If you actually would like a loan, I need to know specifics of what it is for, how long it will take you, what sort of interest you are willing to pay, late fees you will pay, ect.
If you are serious, please post in depth either here, or in PM.

My last investment returned a great deal of interest, now I have a lot of BTC to lend. I will lend up to 25 BTC, all individuals must be legitimate. I am looking for about 4% interest a year, lending terms between 1 month to a year. If you would like to contact me about this, please PM me with your contact information.

Users, be cautious of this user. He didnt scam me, nor am I claiming he is a scammer... but he refused to do increments because "I do not have too much time for small transactions." ; Well these payments are instant, I dont see how sending back and forth a few payments, instead of one large one, takes that much time. Instead of spending the extra 2 minutes to use increments, he decides to have a 20 minute debate about how he is trusted and I should go first.

Thanks for the rain!

I by no means am trying to say the total bitcoins mined is not finite, I am trying to say how we get there is not set in stone. At the rapid growth Bitcoin is offering, I would be surprised if it didn't get snatched up by some corporation trying to manipulate the system. We dont even know if we will have enough food supply 100 years from now, who knows if we will have the electricity, internet, or bitcoin around then.

This is true, however the adjustment period it is still vulnerable to manipulation. If I spent 100 million USD on research and development of mining equipment, and I was in sole control and custody of the machine. I could easily disrupt the mining process by mining blocks selectively. Lets say I crash the party and start up my miner at the beginning of the block, I could easily find it within (for the sake of the argument) say 10 seconds. The difficulty would change tremendously in order to account for this increase of mining speed. Then lets say I turned off my miner, the other mining equipment could take a while before finding a block at the adjusted rate. Essentially nothing is finite in the blockchain system, no matter how much everyone thinks it is. You can argue the date on when the last bitcoin will be mined, but given that this is the first of its kind my guess is still; the date is unknown.

I don't understand why there are so many comments stating "useful graph", no offense but this graph is highly inaccurate. Taking a look at only one of your windows, you state that block 210k would of been at the start of 2013; actually the block 214563 marked the beginning. You estimate 420,000 at the start of 2017; when comparing the growth between now and the block in 2013, we should be at roughly 450k (my calculations were roughly 449534). Being off 10,000 blocks here and 30,000 blocks there might not seem like much to you, but it means a world of difference when this is potentially our future lifeline (at least influencing it). Thank you for your efforts to help the community, I do not mean to point out your errors in an aggressive manor; I hope you don't see it this way. I just advise people to carefully evaluate any data when making important decisions, especially this data.

I do not believe one can accurately calculate and/or estimate when all Bitcoins will be mined. There are many factors such as mining profitability, technological advancements in mining speed, the demand for Bitcoins, collapses of certain global economies, and countless other variables. What we do know is that the last block containing new bitcoin will be the block 6,930,000 ; we are currently on block 312,450 (at the time of this posting). The estimation given is based off block speeds being under 10 minutes per block. With even the slightest change in speed, the date could be prolonged. If calculating the average block speed at 15 minutes, it would be late 2202. Keep in mind when trying to estimate what the average block speed is, todays speed is only a small window in time. With increasing difficulty, the future could hold hour long block times if our technology does not increase. Alternatively if one were to develop an unthinkable mining rig with speeds unimaginable, they could quickly be pumping out blocks every few seconds.

Overall, to answer your question; We will never know when the last bitcoin will be mined until it happens.

If you are concerned as to what would happen once the last coin is mined, all the transaction fees would go to the pool that finds the block. The transaction fees would be divided up and serve as *hopefully* a substantial reward.

I do see that this thread was created in 2011, and probably longer relevant towards the current Satoshi Client; I would still like to thank you for your efforts in closing the gap between developers and users. I have been picking apart some of the older clients as well and with the way the code is laid out, it can quickly become overwhelming. Although my findings were similar to yours, it was a pleasurable read that helped me evaluate my findings with a better since of clarity.
