Throughout 2017, Bitcoin and the broader crypto market experienced one of the most extraordinary bull runs in financial history. Bitcoin started the year at around $1,000 per coin. By December, it had reached nearly $20,000 — a 20-fold increase in twelve months. Crypto was on every television channel, in every newspaper, at every dinner party. Regular people were asking their financial advisors about Bitcoin. Some were emptying their savings accounts to buy at whatever price they could get.

The 2017 bull run was driven by several factors. The ICO boom brought in billions of dollars of new money and attention. Institutional interest was growing — the CME and CBOE launched Bitcoin futures in December 2017, giving traditional investors a way to bet on Bitcoin without holding it. Fear of missing out drove retail investors to buy at any price. Social media was full of stories of teenagers and college students becoming millionaires overnight.

The euphoria was extreme. Bitcoin Cash forked off Bitcoin in August, creating a new multi-billion-dollar coin. Ethereum went from $8 at the start of the year to over $1,400 by January 2018. Ripple’s XRP went from less than a cent to over $3. New ICOs were selling out in seconds. Friends of friends were quitting their jobs to trade crypto full-time. It felt like a gold rush, and everyone wanted a piece.

The peak came on December 17, 2017. Bitcoin briefly touched $19,783 on Coinbase and over $20,000 on some other exchanges. Traders watched their screens in amazement. Many were paper millionaires. A small number of early adopters had become paper billionaires. The total market cap of all cryptocurrencies exceeded $800 billion. It was a surreal moment.

And then it all came crashing down. Within weeks, Bitcoin began a brutal decline. By February 2018, it had fallen to $6,000. By December 2018, it was below $3,200. Most altcoins fell even harder — 90%, 95%, some went to zero. The “crypto winter” of 2018 would last two years, a bear market even more severe than 2014. Fortunes were lost. Millions of new investors — who had bought at the top — saw their portfolios devastated. Media coverage turned from euphoric to mocking. Bitcoin was declared dead, again, for the 300th time. But those who had been through 2011 and 2014 knew the script: winter was just another phase of the cycle, and spring would come.

One of the biggest problems in crypto trading has always been the difficulty of moving between crypto and fiat currency. Every time a trader wanted to take profits by converting to dollars, they had to either sell on an exchange that supported fiat (limited options, lots of regulation) or hold their gains in something volatile like Bitcoin. In 2014, a company called Tether proposed a solution: a cryptocurrency pegged 1:1 to the U.S. dollar.

Tether (USDT) worked by claiming that for every token issued, the company held one dollar in its bank accounts as reserve. If you wanted to “sell” crypto for dollars, you could just trade your Bitcoin for USDT. The price would stay at $1.00 because the reserves backed it. You could hold USDT as cash, trade it on multiple exchanges, move it between wallets — all without dealing with banks.

The appeal was immediate. Traders loved having a stable asset they could trade in and out of. Exchanges loved having a dollar-like token that didn’t require banking relationships. USDT became one of the most traded cryptocurrencies in the world, often surpassing even Bitcoin in daily volume. By 2024, more than $100 billion worth of USDT was in circulation.

But Tether has been shrouded in controversy for years. Critics questioned whether the company actually held enough dollars to back all the USDT in circulation. Audits were promised and delayed. The company had shifting explanations of what backed the reserves — sometimes dollars, sometimes “cash equivalents,” sometimes loans and commercial paper. In 2021, the New York Attorney General fined Tether $18.5 million for misrepresenting its reserves. Skeptics argued that Tether could collapse at any moment, potentially taking down the entire crypto market with it.

Despite the controversies, Tether has not collapsed. It remains the most widely used stablecoin in crypto. Its competitors — USDC from Circle, BUSD from Binance, DAI from MakerDAO — have taken market share but never fully displaced it. Tether’s existence has been crucial to crypto’s development. Without a reliable way to hold “dollars” on-chain, DeFi couldn’t exist. Trading would be much harder. The crypto economy would look very different. Whatever you think of Tether’s practices, its impact on the industry is undeniable.

Throughout 2016 and especially 2017, the crypto world experienced something unprecedented: a fundraising frenzy driven by Initial Coin Offerings (ICOs). Projects would launch websites, write whitepapers, create ERC-20 tokens, and sell them to the public. In exchange, investors received tokens that might become valuable if the project succeeded. By the peak of 2017, hundreds of new ICOs were launching every month, collectively raising billions of dollars.

The appeal was obvious. For projects, ICOs were a way to raise money without dealing with venture capitalists, regulators, or legal complexity. For investors, they were a way to get early access to projects that might become the next Ethereum — with potentially massive returns. The ICO format was borderless: anyone with an internet connection and some ether could participate. This democratized access to early-stage investing in a way that had never been possible before.

Some ICOs were serious projects that went on to become important. Filecoin raised $257 million in 2017 and built a real decentralized storage network. Tezos raised $232 million and became a major smart contract platform. Bancor, Golem, Status, Basic Attention Token — all raised tens of millions and delivered functional products. These projects contributed real value to the crypto ecosystem.

But the vast majority of ICOs were either outright scams or hopeless pipe dreams. Projects with no technical team, no working product, and no realistic plan raised tens of millions of dollars from enthusiastic investors. Many founders simply ran away with the money — “exit scams” that left investors with worthless tokens. Others spent the money on salaries and marketing without ever shipping a working product. A 2018 study found that over 80% of 2017 ICOs had either failed or were identified as scams.

The total amount raised in ICOs during 2017 was staggering — approximately $5.6 billion by some estimates. It was the largest wealth transfer from retail investors to crypto entrepreneurs in history. Regulators eventually noticed. The SEC began declaring that many ICO tokens were unregistered securities. China banned ICOs outright in September 2017. By mid-2018, the ICO bubble had burst, and most of those 2017 projects were dead. But the ICO era had demonstrated something important: there was enormous pent-up demand for early-stage crypto investing, and the traditional financial system was completely unprepared to meet it.

In November 2015, an Ethereum developer named Fabian Vogelsteller published a proposal called EIP-20. It described a simple standard for creating tokens on the Ethereum blockchain. Any developer could follow this standard to create a token that would be compatible with wallets, exchanges, and other infrastructure. The proposal was accepted and renamed ERC-20 (“Ethereum Request for Comment 20”). It would become the most important technical standard in crypto history.

Before ERC-20, creating a cryptocurrency required building an entirely new blockchain. You needed miners, nodes, wallets, and exchanges to support your coin. The barrier to entry was high, which is why there were only a few hundred cryptocurrencies in 2015. After ERC-20, creating a token became trivial. A developer could write a few dozen lines of Solidity code, deploy it to Ethereum, and they had a fully functional token. No blockchain needed. No miners needed. No infrastructure needed.

This simplicity unleashed a tsunami of tokens. In 2016, a few dozen ERC-20 tokens existed. By 2017, there were thousands. By 2018, tens of thousands. Every ICO in the 2017 bubble used ERC-20. Every DeFi protocol used ERC-20 for its governance token. Every meme coin, every celebrity endorsement, every marketing gimmick could be turned into an ERC-20 token. The standard had democratized token creation — for better and for worse.

ERC-20’s simplicity was its genius. The standard defined just a few functions: transfer, balanceOf, totalSupply, approve, allowance. That was enough to make tokens interoperable. An ERC-20 token from one project could be traded on a decentralized exchange, stored in a wallet, lent on a lending platform, and used in a game — all using the same interface. The standard created a universal language for tokens on Ethereum.

The impact of ERC-20 extended far beyond Ethereum. Other blockchains copied the pattern. BEP-20 on Binance Smart Chain. TRC-20 on Tron. SPL on Solana. The idea that tokens should be interoperable standards, not custom implementations, became a core principle of the entire crypto industry. ERC-20 is sometimes criticized today for being too simple — it doesn’t handle edge cases well, and better standards like ERC-777 and ERC-1155 have been proposed. But its simplicity was exactly what made it successful. Sometimes, the most impactful innovations are the ones that make hard things easy.

After The DAO hack of June 2016, the Ethereum community faced an agonizing decision. The 3.6 million stolen ether sat in a time-locked “child DAO” that the attacker couldn’t access for 28 days. The community had that window to decide: accept the theft as an unavoidable consequence of “code is law,” or modify the Ethereum blockchain itself to reverse the theft and return the funds.

The debate was intense and philosophical. Purists argued that the whole point of a blockchain was immutability — if you could reverse transactions when something went wrong, then blockchains were no different from traditional databases. Pragmatists countered that $50 million in stolen funds was too much to accept, especially when the theft was the result of a bug, not a consensus failure. Vitalik Buterin initially sided with the purists but eventually supported the fork.

On July 20, 2016, Ethereum executed a “hard fork” — a permanent modification of the blockchain’s code. The fork effectively rewrote history at the block where the DAO hack occurred, moving the stolen ether to a recovery contract where the original owners could reclaim their funds. The vast majority of the Ethereum community followed the hard fork, and the main Ethereum chain continued under the same name.

But a minority of users refused to follow the fork. They believed that intervening to reverse transactions — even to undo a theft — betrayed the core values of blockchain. They continued to mine and use the original, unmodified chain, which became known as Ethereum Classic (ETC). This was Ethereum’s first major community split, and it established a precedent: when a blockchain community faces an existential disagreement, they can fork and go their separate ways.

In the years since, Ethereum and Ethereum Classic have had very different trajectories. Ethereum (ETH) has become the dominant smart contract platform, home to DeFi, NFTs, and countless innovations. Ethereum Classic remains a smaller, more conservative chain with a devoted but niche community. The 2016 fork taught the crypto world an important lesson: decentralization doesn’t mean everyone agrees. Sometimes the best way to resolve a conflict is for both sides to go their separate ways and let history judge who was right.

In April 2016, a group of Ethereum developers launched one of the most ambitious experiments in blockchain history: The DAO (Decentralized Autonomous Organization). The DAO was designed to be a venture capital fund controlled entirely by smart contracts on the Ethereum blockchain. Token holders would propose investments, vote on them, and the smart contracts would automatically distribute funds to approved proposals. No partners, no lawyers, no human middlemen — just code.

The fundraising period for The DAO was extraordinary. Over 28 days, participants sent ether to The DAO’s smart contract in exchange for DAO tokens. By the end of the token sale, The DAO had raised approximately 12 million ether — worth around $150 million at the time. It was the largest crowdfunding event in history, surpassing the Ethereum ICO itself. Over 11,000 participants became DAO token holders.

The DAO captured imaginations beyond the crypto community. Here was a fully autonomous organization, controlled by token holders, that would make investment decisions algorithmically. It was the embodiment of the “code is law” philosophy. Media coverage was enthusiastic. Legal scholars debated what The DAO meant for corporate law. Governance researchers studied its voting mechanisms. For a few weeks in mid-2016, The DAO seemed like the future.

Then disaster struck. On June 17, 2016, an attacker exploited a bug in The DAO’s smart contract code. The bug was in a function called “splitDAO,” which allowed token holders to split off from the main DAO and create their own mini-DAO. Due to the way the code was written, the attacker could repeatedly call the split function while withdrawing ether, effectively draining funds faster than the contract could update its records. Over several hours, the attacker siphoned 3.6 million ether — worth about $50 million.

The hack shocked the Ethereum community. The stolen funds were safely in a “child DAO” that couldn’t be accessed for 28 days due to the contract’s time lock. This gave Ethereum developers a window to respond. But what to do? Reversing transactions on a blockchain was supposed to be impossible — that was the whole point. Yet letting the attacker walk away with $50 million seemed intolerable. The community faced a choice that would define Ethereum for years to come: stick with “code is law,” or intervene to save the users. The answer would split the community forever.

The most revolutionary feature Ethereum introduced was smart contracts — programs that run on the blockchain and execute automatically when certain conditions are met. The term was actually coined by Nick Szabo in the 1990s, but Ethereum was the first platform where smart contracts became practical. A smart contract can hold money, send money, interact with other contracts, and enforce complex logic without any human intervention.

To understand why this matters, consider a simple example. Suppose Alice wants to send Bob $100 every month for one year. In traditional banking, she would set up a recurring transfer. But she has to trust her bank to execute it correctly. If the bank fails, if Alice dies, if her account is frozen — the payments might stop. With a smart contract, Alice can lock $1,200 into a contract that automatically releases $100 to Bob each month. No bank needed. No trust required. The code executes as written.

This simple idea opens up enormous possibilities. Insurance policies that automatically pay out when flight delays are recorded by an oracle. Lending platforms where interest accrues and is distributed automatically. Decentralized exchanges where trades happen without an intermediary. Voting systems where tallies are mathematically guaranteed. Supply chain tracking where every transfer is verified cryptographically. All of this becomes possible when you can write logic into money itself.

Smart contracts also come with serious risks. Once deployed, they’re immutable — you can’t fix bugs after the fact. If there’s a mistake in the code, attackers can exploit it to drain funds. If the logic has unintended consequences, you’re stuck with them. The early years of Ethereum featured many painful lessons about smart contract security, culminating in The DAO hack of 2016, which would cost users millions of dollars.

The phrase “code is law” captured the early Ethereum philosophy. The idea was that smart contracts would replace courts and lawyers and intermediaries. Human judgment was fallible and corruptible; code was precise and predictable. Over time, this philosophy would soften. The community would learn that code has bugs, that human judgment is sometimes necessary, and that total immutability isn’t always desirable. But the core insight remained: smart contracts enabled a new kind of digital interaction, where the rules were transparent, the execution was automatic, and nobody had to trust anybody else.

After more than 18 months of development, the Ethereum network finally went live on July 30, 2015. The first block — Ethereum’s version of the Bitcoin genesis block — was mined at 15:26 UTC. For the crypto community, this was a momentous occasion. For the first time, the world had a general-purpose blockchain with a built-in programming language. The era of smart contracts had officially begun.

The launch was modest. Ether traded at around $0.75 per coin in the first days after launch. Few applications were live yet. Most of the activity was developers experimenting with the new platform, writing simple smart contracts to understand how everything worked. But the infrastructure was there, and it was real. You could write a program in Solidity, deploy it to the Ethereum network, and anyone in the world could interact with it.

The early Ethereum community was a fascinating mix. There were Bitcoin refugees — people who believed in crypto but thought Bitcoin was too conservative. There were academics excited about the theoretical possibilities. There were libertarians who saw smart contracts as a way to build a stateless society. And there were entrepreneurs who saw Ethereum as a platform for building new kinds of internet businesses.

Ethereum’s launch was called “Frontier” — the first of several planned phases of the network’s development. Frontier was deliberately rough and experimental. Gas fees were unpredictable. The interface was primitive. Transactions sometimes failed for mysterious reasons. But for the adventurous developers who showed up, it was an incredible playground. You could build almost anything you could imagine, limited only by your coding skills and the network’s computational resources.

In the months following launch, Ethereum began to capture attention. Developers started building decentralized applications — “dapps” — that demonstrated what smart contracts could do. Prediction markets, crowdfunding platforms, decentralized exchanges, identity systems. Most were rough prototypes. A few would evolve into the foundations of entire industries. When Ethereum launched in July 2015, nobody could have predicted what it would become. But the seeds had been planted, and the soil was ready.

In July 2014, the Ethereum Foundation launched one of the most important crowdfunding events in crypto history: the Ethereum pre-sale, or ICO (Initial Coin Offering). For 42 days, anyone in the world could send bitcoins to an Ethereum-controlled address and receive ether (ETH) tokens in return at a rate of roughly 2,000 ETH per 1 BTC. The goal was to raise enough money to fund Ethereum’s development through launch.

The ICO format was revolutionary. Traditional startups raise money from venture capitalists who have strict legal requirements and take large equity stakes. Ethereum had no such constraints. Anyone, anywhere in the world, could become a funder of the project. The only thing they needed was Bitcoin and an internet connection. In exchange, they received pre-launch ETH tokens that would become valuable (or worthless) depending on whether the project succeeded.

The Ethereum pre-sale raised approximately 31,000 BTC — worth about $18 million at the time. It was the largest crypto crowdfunding ever, and enormous by 2014 tech startup standards. The funds would be used to pay developers, legal costs, and infrastructure. By crypto standards, it was an enormous war chest for a team that included some of the brightest minds in blockchain technology.

The ICO also set a template that would be imitated — and often abused — for years to come. Hundreds of other projects would copy Ethereum’s approach, launching their own ICOs to raise money from retail investors. Most would be scams, vaporware, or well-meaning failures. But a handful would succeed and become major projects. The ICO era that began with Ethereum would reach its peak in 2017, with billions of dollars flowing into dubious projects, before crashing spectacularly.

For people who bought ether during the pre-sale, the returns were staggering. At the sale price of roughly $0.30 per ETH, a $1,000 purchase bought about 3,333 tokens. At Ethereum’s all-time high of around $4,800 in 2021, those tokens would be worth about $16 million. Few investments in history have produced such extraordinary returns. The Ethereum ICO is now remembered as possibly the greatest fundraising success story in the history of crypto.

In late 2013, a 19-year-old Vitalik Buterin was deeply immersed in the Bitcoin world. He was writing for Bitcoin Magazine, contributing to open-source projects, and traveling the world to meet other crypto pioneers. During this period, he saw Bitcoin up close and identified what he considered its fundamental limitation: Bitcoin was a great currency, but it wasn’t a general-purpose platform for decentralized applications. You couldn’t build complex things on top of it.

Buterin proposed adding a scripting language to Bitcoin that would allow more complex smart contracts. The Bitcoin community mostly rejected the idea. Bitcoin was supposed to be simple, secure, and focused — adding complexity would introduce risks. Rather than fight this battle, Buterin decided to build a new platform from scratch, one designed from the ground up to support arbitrary computation.

In December 2013, Buterin published the Ethereum whitepaper: “A Next-Generation Smart Contract and Decentralized Application Platform.” The paper proposed a blockchain with a built-in Turing-complete programming language. Instead of just tracking who owned how much of a single currency, Ethereum would track the state of arbitrary programs — “smart contracts” — that could be anything from financial instruments to games to entire decentralized organizations.

The key innovation was the Ethereum Virtual Machine (EVM), a virtual computer running on every node in the network. Developers could write code (in a language called Solidity), deploy it to the EVM, and anyone in the world could interact with it. No permission needed. No central authority. Smart contracts would execute exactly as written, enforced by cryptography rather than courts.

Buterin’s paper attracted immediate attention. Within weeks, he had assembled a team of co-founders — Gavin Wood, Joseph Lubin, Charles Hoskinson, and several others. By early 2014, the project was underway. Ethereum would go on to become the second-most-valuable cryptocurrency in the world, the foundation for an entire ecosystem of decentralized applications, and arguably the most significant innovation in crypto since Bitcoin itself. But in December 2013, it was just a PDF written by a teenager who thought Bitcoin was too limited.
