# Total Supply of ETH

Member Posts: 2
What's the totally amount of ETH that will be created?
How many are created for the IPO?
How many years will it take to mine the rest?

10^18 if I'm reading http://ethereum.org/ethereum.html correctly. Mining will tail off over decades.

I don't know if 1 ether = 10^18 wei or 1 wei = 10^18 ether. Can someone clarify that please?

Mining won't actually tail off, ever. A constant amount of ETH will be mined forever. But what happens is over time, as more and more ETH are mined, the constant amount mined becomes a smaller and smaller portion of the total amount of existing ETH. The % mined of the total existing amount tends to 0% over time, asymptotically, never actually reaching 0%.

Additionally, an equilibrium will eventually be reached when the rate of ETH lost due to bitrot, carelessness, deaths, etc. equals the rate of new ETH mined.

My take was 1 ether = 10^18 wei

So how many total number of coins? 10 ^ 18 eth will be created + x % every year?

The total number of coins that will be created in the genesis block:

X * 1.5 where X equals the total number of ethereum purchased in the IPO phase (1 BTC = 1000 - 2000 ether, depending on when you buy).

Every year, 0.4X will be mined. So the supply of ether at the end of Year 1 will be X + 0.5X + 0.4X = 1.9X, at the end of Year 2 it will be 2.3X, or 2.7X for Year 3, and so on.

So if all 30,000 BTC are invested in the first week and the IPO closes, you will have:

60,000,000 ether * 1.5 = 90,000,000 ether to start, and an additional 24,000,000 ether mined each year (40% of the 60,000,000 initial ether).

On the other hand, if only 1,000 BTC are raised, and they are all raised during the last week of the IPO when 1 BTC = 1,000 ETH, then:

1,000,000 * 1.5 = 1,500,000 ether to start and an additional 400,000 mined each year.

It all depends on how much ether is "created" as a result of the IPO.

Here is how I understood coin generation:

There will be some percentage of coins lost per year. So, if the supply of new coins was cut off at some point, you'd have deflation as coins are lost over time. With Etherium, the intent is that currency supply will increase until the amount being created each year is offset by the number of coins lost per year. (The currency increase is a flat 40% of the initial base, whereas the loss is some percent of the current total base.)

Be aware there are those out there who are spreading a lot of FUD about inflation. Yes, ethereum has inflation, but so does bitcoin (until block rewards halved, 2.6 million btc were being created--that's inflation--per year. Now it's down to 1.3 million).

I think the amount of inflation is unfair to the IPO investors. What's the point of investing with such high inflation?

The rate of inflation and the initial allocation do not matter nearly as much as the fact that the rate is an immutable value. The reason fiat currencies create so many disasters is that their rate of inflation is in the hands of central planners who don't understand the economy nearly as well as they think they do.

So don't be too bothered with the method the devs have chosen for their fundraiser. The developers who invented this thing should be free to name their price. In the long term, Ethereum is going to sink or swim on the merits and adoption of the platform, and nothing else. I'm optimistic but only time will tell.

What about Bitcoin's rate of inflation? The number of BTC went from 0 to 2.6 million in Year 1, to 5.2 million in Year 2, to 7.8 million in Year 3...that's some pretty damn serious inflation too!

Nor does the ethereum protocol after it is created it is open source and available to all even if you did not fund ether or use it.
