Bitcoin turns 18: from cypherpunk whitepaper to Wall Street asset

Bitcoin reaches its 18th birthday

Bitcoin turns 18 on October 31, 2026 — eighteen years since the pseudonymous creator Satoshi Nakamoto posted the Bitcoin whitepaper, Bitcoin: A Peer-to-Peer Electronic Cash System, to a cryptography mailing list. The network itself went live when the first block, called the genesis block, was mined on Jan. 3, 2009.

A Cointelegraph magazine retrospective published the same day traces that journey, from early experiments and exchange collapses to the coin's embrace by traditional finance — and flags the open questions hanging over its future.

Key points

• Bitcoin was created to remove the need for trust in financial transactions and to bypass opaque institutions.


• The first block carried a quote from a Times headline: "Chancellor on brink of second bailout for banks" — a nod to the financial crisis backdrop.


• The coin has survived two major exchange collapses (Mt. Gox and FTX) and two Chinese bans, and crossed $100,000 for the first time at the end of 2024.


• Open concerns now include the $6.3 billion Binance hack, quantum computing, and AI-related cyber threats.

Milestones from the early years

One of the most famous early moments came on May 22, 2010, when developer Laszlo Hanyecz paid 10,000 BTC for two pizzas — one of the earliest documented Bitcoin transactions. The day became known as Bitcoin Pizza Day. The coins were worth about $41 at the time; per the magazine's estimate, they would be worth around $780 million at recent prices.

Bitcoin traded for pennies in its earliest days, then broke $1,000 for the first time in late 2013. That run ended in February 2014, when Mt. Gox — then the world's largest Bitcoin exchange — stopped trading and went offline. Around 850,000 BTC, including customers' funds, were lost, making the exchange an early symbol of the phrase "not your keys, not your coins."

Bans, forks and the 2017 rollercoaster

In 2017, Bitcoin climbed from below $1,000 in January to almost $20,000 by December, alongside a boom in initial coin offerings (ICOs) — token sales that promised blockchain projects for everything from banking to supply chains, and even iced tea. JPMorgan Chase CEO Jamie Dimon called Bitcoin "a fraud" in September 2017 and said he would fire any employee trading it.

The same year, the "block size war" — a bitter dispute over how the network should scale — peaked in August 2017 with a hard fork that created Bitcoin Cash. China banned ICOs in September 2017 and moved against exchanges. Separately, Australian computer scientist Craig Wright repeatedly claimed to be Satoshi Nakamoto; the UK High Court rejected that claim in 2024.

FTX, the second China ban and the ETF era

Bitcoin's next big rally came during the pandemic, after governments and central banks flooded markets with money. The price reached almost $69,000 by November 2021, despite China's sweeping ban on crypto transactions and mining announced in September 2021.

In November 2022, the FTX exchange collapsed, deepening the crypto winter and triggering what the industry called "Operation Chokepoint 2.0" — a period of regulatory hostility and lost trust from traditional finance.

The turn came in January 2024, when the US Securities and Exchange Commission approved the first US spot Bitcoin ETFs — funds that let investors gain exposure to BTC through regulated markets without managing wallets or private keys themselves. Bitcoin broke $100,000 for the first time at the end of that year, and hit a new all-time high of more than $126,000 in October 2025, according to the magazine.

From rebel to regulated asset

Bitcoin is now firmly tied to traditional finance. The GENIUS Act has set up a federal framework for stablecoins (tokens pegged to assets like the dollar), the SEC has offered more clarity on how securities laws apply to crypto, and Europe's MiCA regulation has harmonized rules for the local industry. Banks have moved into custody and trading services, and even Dimon shifted from dismissal to allowing clients to buy the asset.

That shift has drawn criticism from within. Many Bitcoiners question whether institutions holding large amounts of BTC are concentrating ownership and centralizing supply — and whether the cypherpunk movement has been captured by the very institutions it set out to rebel against.

What is still unclear

Security questions remain open. Many fear quantum computing could eventually break the cryptography that secures Bitcoin. A proposed upgrade called BIP-360 outlines a new type of Bitcoin output designed to reduce certain quantum vulnerabilities — but as the block size war showed, agreeing on changes to a decentralized system is hard, and no implementation timeline is settled.

The magazine also points to this week's $6.3 billion Binance hack — described as the largest crypto exchange hack on record — and AI-related cyber threats as reasons the question of long-term security is still looming. Per the source, the hack has renewed fears about the security of centralized exchanges and the stability of crypto infrastructure.

Why this matters

Eighteen years in, Bitcoin has moved from a mailing-list experiment to a regulated financial product with Wall Street involvement. The trade-off at the center of the debate is between that mainstream acceptance and the original goal of a trustless, decentralized system — a tension the community has not resolved, and one that new security challenges and proposed protocol changes will keep testing.
