Ethereum celebrated its sixth anniversary on July 30, 2021, coinciding with the successful London hard fork upgrade—a major milestone in its development. This analysis reviews key on-chain, market, and network performance metrics over the past six years, highlighting Ethereum’s remarkable growth and resilience.
Market Performance: Price, Market Cap, and Circulation
Ethereum’s native token, ETH, has seen extraordinary appreciation since its inception. On August 7, 2015, ETH was trading at approximately $2.77, with a market capitalization of around $200 million. As of August 4, 2021, the price had surged to $2,725.72, and the market cap reached approximately $318.84 billion—representing a 984x increase in price and a 1,594x expansion in market value over six years.
The all-time high was recorded on May 11, 2021, when ETH hit $4,181.28, nearly 2,090 times the initial price.
Regarding supply, the circulating amount of ETH grew from 72 million at launch to 117 million by July 30, 2021—a 62.5% increase. The annual growth rate has slowed over time: from over 13% in 2016 and 2017 to just 4.54% in 2020. The introduction of EIP-1559 as part of the London upgrade is expected to alter ETH’s emission model, potentially leading to a deflationary trend in the long term.
User Adoption: Address Growth and Activity
Ethereum has witnessed explosive growth in user adoption. The number of unique addresses has soared from just over 1 million in 2015 to more than 165 million by August 4, 2021—an increase of over 16,500 times.
Annual growth rates were highest between 2016 and 2018, with increases of 2,237%, 1,847%, and 194%, respectively. In 2019 and 2020, growth moderated to around 55% per year. So far in 2021, unique addresses have grown by 26%. If growth continues at the previous two-year average of 55%, the network could surpass 200 million addresses by the end of the year.

Transaction Volume and Network Usage
On-chain transaction activity reflects the expanding utility of the Ethereum network. Annual transaction counts have risen dramatically:
- 2015: 1.06 million
- 2016: 13.66 million
- 2017: 103 million
- 2018: 251 million
- 2019: 243 million
- 2020: 345 million
As of August 2021, annualized transaction volume is on track to exceed the previous year.
The average number of daily transactions has also climbed consistently, from about 6,800 in 2015 to nearly 1.29 million in 2021—a 36% increase over 2020 levels. The London upgrade aims to reduce congestion and high fees during peak usage, which may further boost transaction throughput and user experience.
In terms of value settled, 2017—the year of the ICO boom—remains the peak for annual transaction volume in ETH terms, with 43.45 billion ETH moved. In other years, the average annual settlement value has hovered around 7.1 billion ETH. The daily average settlement value in 2021 reached 3.18 million ETH, a 413% increase from 2015.
Gas Fees: Rising Costs and Upgrade Impact
Average gas prices have followed a “V-shaped” trajectory over the past six years. After declining from 2015 to 2019, the average fee rose sharply in 2020 to 60.56 Gwei—a 274% year-over-year increase. So far in 2021, the average gas price is 104.77 Gwei, the highest annual average ever, representing a 73% increase over 2020 and 33% over 2015.
The London hard fork introduces a new fee market mechanism designed to make transaction costs more predictable and less volatile, which may help moderate average gas prices in the future.
Network Security: Hash Rate and Mining Growth
Ethereum’s network security, as measured by hash rate, has strengthened significantly over the years. Annual average hash rate figures are as follows:
- 2015: 0.40 TH/s
- 2016: 3.67 TH/s
- 2017: 63.64 TH/s
- 2018: 248.54 TH/s
- 2019: 168.85 TH/s
- 2020: 210.98 TH/s
Year-over-year growth rates were highest in 2016 and 2017 (818% and 1,634%, respectively), with a moderate recovery of 25% in 2020 after a decline in 2019. As of August 4, 2021, the average hash rate is 485.65 TH/s—a 131% increase over 2020 and a 1,213% increase over 2015.
The hash rate on August 4, 2021, reached 583.15 TH/s, nearly 58,300 times the level at launch. This growth underscores the expanding mining participation and heightened security of the network—even as it prepares for the transition to Ethereum 2.0 and proof-of-stake.

Frequently Asked Questions
How has Ethereum’s price changed since launch?
ETH’s price rose from around $2.77 in August 2015 to over $2,700 by August 2021—a gain of nearly 984x. Its market cap grew from $200 million to over $318 billion in the same period.
What is the current transaction capacity of Ethereum?
The network currently processes about 1.29 million transactions per day on average, up 36% from 2020. The London upgrade is expected to improve throughput and fee predictability.
How many people use Ethereum?
There are over 165 million unique addresses on Ethereum, growing at about 26% so far in 2021. If growth continues, the network could reach 200 million addresses by year-end.
What was the impact of EIP-1559?
EIP-1559 introduced a new fee mechanism that includes burning a portion of transaction fees, potentially making ETH a deflationary asset over time and improving user experience regarding gas costs.
How has network security evolved?
Hash rate has increased over 58,000 times since 2015, reflecting greater miner participation and enhanced network security—even as Ethereum moves toward proof-of-stake.
What is the significance of the London upgrade?
The London hard fork introduced EIP-1559 and other improvements aimed at reducing fee volatility, improving transaction efficiency, and setting the stage for Ethereum’s eventual transition to Ethereum 2.0.
