The primer on Crypto in 2026

In 2010, Laszlo Hanyecz traded 10,000 bitcoins (then worth $41) for two pizzas. Laszlo considered the exchange to be “free pizza” as he was mining several thousand BTC a day. Those BTCs are now worth around $777 million. Who knew back then… doesn’t need to work today.

Bitcoin’s origin story reads like a spy thriller. In 2008, Satoshi Nakamoto published a nine-page whitepaper describing a wild idea: digital money that worked without banks or governments. No central authority. Just code and cryptography. Satoshi launched the network in 2009, mined some early coins, and then vanished into the digital void in April 2011.

The hunt to find him was on. In hindsight, Satoshi’s operational security was extraordinarily careful. Despite years of communication, no confirmed personal information was ever leaked. People became convinced that ‘Satoshi’ was a pseudonym. Nearly every prominent cryptographer has been suggested. Entrepreneurs like Jack Dorsey and Elon Musk were accused. Documentaries and movies were made. For years, all suspects denied their involvement. The elusive billionaire (Satoshi controls around 1M coins but never moved them) could not be found. Finally, an extensive investigation in 2026 by The New York Times analyzed the writing style of Satoshi and identified a perfect match: Adam Back, a British cryptographer. Back denies being Satoshi, chalking it up to ‘coincidence’.

Bitcoin’s genius lies partly in scarcity. Only 21 million bitcoins will ever exist - a hard cap written into the code. In a world where governments can print unlimited money, Bitcoin’s fixed supply means it must grow in value as demand increases. This scarcity even one-ups gold. One day we might be able to cheaply transform mercury into gold, or catch a golden asteroid. But once the last bitcoin gets mined, there won’t be more, ever.

This captures people’s imagination. Bitcoin’s market cap today is bigger than Visa, Mastercard, and Amex combined. If those three companies vanished, the world would panic. Trade would collapse and people would starve. If Bitcoin vanished? A few hundred million people would be upset, but the world would keep spinning. Even El Salvador, where Bitcoin is legal tender, mostly uses US dollars now.

Bitcoin is just not very practical for buying coffee. The network fees are high and the transfers are slow. Bitcoin’s on-chain transaction capacity is roughly 7 TPS (transactions per second), while Visa can handle 65,000+ TPS (they typically do around 1,700 TPS). On top of that, Bitcoin’s mining process - keeping the network secure - is extremely power hungry by design. It consumes as much electricity as some small countries. The Bitcoin community resists change, so innovation happens elsewhere.

Enter Ethereum. In 2013, Vitalik Buterin (then 19 years old) proposed the idea of a programmable blockchain - a world computer that could run any program, not just transfer value. Working with six other co-founders, Ethereum launched in 2015 and created an entirely new ecosystem. Smart contracts let developers write self-executing agreements locked into the blockchain - basically, if X happens, the code automatically does Y without needing a middleman. NFTs (non-fungible tokens) became digital collectibles with proof of ownership on the blockchain. DeFi (decentralized finance) let people lend, borrow, and trade without banks. Using these platforms costs “gas fees” - tiny payments paid to validators who process your transaction. Ethereum became the playground for both brilliant ideas and wild experiments. It also became a cautionary tale: in 2016, a famous DAO (decentralized autonomous organization) was hacked due to smart contract vulnerabilities. $50 million disappeared. The aftermath was messy. While the funds were reclaimed (in a controversial way), the DAO is now practically dead.

The platform keeps evolving through major upgrades. In 2022, Ethereum shifted from “Proof of Work” (energy-intensive mining) to “Proof of Stake” (energy-efficient validation), cutting energy use by 99.95%.Its base layer capacity remains modest (~100 TPS), but with these add-ons, it might outpace Visa in a few years.

Meanwhile, Solana (SOL) arrived in 2020 as the speed challenger. The founding team, led by Anatoly Yakovenko, were tired of watching crypto networks clog up. Ethereum was choking on its own popularity - gas fees would spike to absurd levels whenever the network got busy. They set to design a blockchain from scratch, specifically for speed. Solana uses an innovative timestamp system called “Proof of History” that lets validators agree on the order of transactions without constant back-and-forth gossip. The result? Solana processes transactions with 400-millisecond finality and fees under $0.001. It’s ridiculously cheap and fast. What does that enable? High-frequency trading bots that would choke on Ethereum. Real-time gaming on blockchain. Streaming payments. Basically, any application that needs speed and low costs can actually work on Solana. Banks like Goldman Sachs, BlackRock, and Citigroup started taking notice because suddenly crypto wasn’t just theoretical - it could actually compete with their settlement systems. Solana became the go-to for traders and institutions tired of waiting around.

Bitcoin laughs this off. It doesn’t aim to be anything more (or less) than digital gold. No fancy features - just a store of value. So far, that strategy worked extremely well. For a few years, the biggest risk for Bitcoin was a government ban. While all crypto is now banned in China, most other governments embrace it. Many central banks are actually doing something once unthinkable - buying crypto to diversify their assets.

Just one problem remains - security. A powerful quantum computer could be used to steal about a third of all bitcoins. These are mostly dormant coins kept in old wallets and include Satoshi’s holdings. The question is not if it’s possible but when. The consensus used to be that we have decades to prepare but recent breakthroughs in quantum computing threw in the shovel: Bitcoin’s encryption could get brute-forced as early as 2029.

Securing Bitcoin against known quantum vulnerabilities is actually not the hard part. Quantum-proof encryptions exist. The challenge is what to do about the vulnerable coins. There are several options, and all are bad. A ‘proper’ fix that would ensure that coins cannot be stolen would ultimately require a hard fork - a breaking change. A hard fork is taboo in the Bitcoin community. If a large chunk of nodes refuses to upgrade, an equivalent of civil war could ensue. Bitcoin could collapse like a house of cards. Will this get fixed the right way, in time?

Prediction: Despite increasing acceptance by businesses and governments alike, crypto remains an extremely risky proposition. The list of once-cool, now-worthless coins is long and will only grow longer. Two cryptos is one more than most people care about. You could win big or lose everything - maybe in a major Bitcoin security incident.
