Is Ethereum Capped Like Bitcoin?

As cryptocurrencies continue to gain popularity, many people are wondering about the differences between them. One of the most common questions is whether Ethereum is capped like Bitcoin. In this article, we will explore the answer to this question and provide you with everything you need to know about Ethereum’s supply limit.

What is Ethereum?

Ethereum is a decentralized blockchain platform that enables developers to build and deploy decentralized applications. It was created by Vitalik Buterin in 2013 and launched in 2015. Ethereum’s native cryptocurrency is called Ether (ETH), which is used to pay for transactions and computational services on the network.

What is Bitcoin?

Bitcoin is the first and most well-known cryptocurrency. It was created in 2009 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin is a decentralized digital currency that operates on a peer-to-peer network, allowing users to send and receive payments without the need for a central authority.

Is Ethereum Capped Like Bitcoin?

The short answer is no, Ethereum is not capped like Bitcoin. Bitcoin has a maximum supply of 21 million coins, while Ethereum does not have a hard cap on its total supply. However, Ethereum does have a yearly issuance limit, which means that the amount of new Ether created each year is limited.

Ethereum’s Yearly Issuance Limit

Ethereum’s yearly issuance limit is currently set at 18 million Ether per year. This means that no more than 18 million new Ether can be created each year, regardless of how much demand there is for it. This limit was put in place to prevent inflation and ensure that the value of Ether remains stable over time.

The Ethereum Ice Age

In addition to the yearly issuance limit, Ethereum has a mechanism known as the “ice age.” The ice age is a difficulty bomb that is built into the Ethereum protocol and is designed to slow down the rate at which new blocks are created. This is done to encourage developers to transition to the new Ethereum 2.0 network, which will use a proof-of-stake consensus mechanism instead of the current proof-of-work mechanism.

Bitcoin’s Supply Cap

Bitcoin’s supply cap of 21 million coins was put in place to prevent inflation and ensure that the value of Bitcoin remains stable over time. The cap was hardcoded into the Bitcoin protocol and cannot be changed without a hard fork.


In summary, Ethereum is not capped like Bitcoin, but it does have a yearly issuance limit and a mechanism known as the ice age to control the rate at which new Ether is created. Bitcoin, on the other hand, has a hard cap of 21 million coins that cannot be changed without a hard fork. While both cryptocurrencies have different supply mechanisms, they are both designed to prevent inflation and ensure that their respective values remain stable over time.


1. What is the current supply of Ethereum?

As of August 2021, the current supply of Ethereum is over 117 million Ether.

2. When will the Ethereum ice age take effect?

The Ethereum ice age is already in effect and is designed to become more difficult over time.

3. Will Ethereum’s supply limit ever change?

It is possible that Ethereum’s supply limit could change in the future, but any changes would require a hard fork and the agreement of the Ethereum community.

4. What happens when all 21 million Bitcoins are mined?

Once all 21 million Bitcoins have been mined, no new Bitcoins will be created. Miners will only receive transaction fees as a reward for processing transactions on the network.

5. How does the supply of Ether affect its value?

The supply of Ether can affect its value, as a larger supply can lead to inflation and a decrease in value. However, Ethereum’s yearly issuance limit and other mechanisms are designed to prevent this from happening.
