Bitcoin vs. Altcoins

Bitcoin Started It All

In 2009, an anonymous person (or group) called Satoshi Nakamoto launched Bitcoin, the first cryptocurrency. For years, Bitcoin was the only cryptocurrency. It proved that digital money could work without banks.

Then people started asking: what else can we build with this technology?

The Birth of "Everything Else"

In 2015, a programmer named Vitalik Buterin launched Ethereum. His idea was simple but revolutionary: what if a blockchain could run programs, not just track money?

Bitcoin is like a calculator: it does one thing (send and receive money) really well. Ethereum is like a smartphone, and you can build apps on it. These apps, called dApps (decentralised applications), opened the floodgates:

• Lending and borrowing without banks (DeFi)

• Digital art ownership (NFTs)

• Games with real economic value

• Automated contracts that execute when conditions are met

Ethereum became the first major programmable Layer 1 blockchain, a platform where other projects could build on top. And it inspired dozens of competitors.

The Layer 1 Race

Once Ethereum proved the concept, other teams said "we can do this faster, cheaper, or better" and built their own Layer 1 blockchains:

• Solana (SOL): Extremely fast (400ms block time), low fees. Popular for trading and memecoins.

• BNB Chain: Built by a major global exchange. Lower fees than Ethereum, huge user base in Asia.

• Cardano (ADA): Academic approach, peer-reviewed research, slower to ship but methodical.

Think of Layer 1s as different cities. Each has its own infrastructure, rules, and culture. People and money flow between them, but each operates independently.

Layer 2s: Building on Top

As Ethereum got popular, it got congested. At peak times, a single transaction could cost thousands of rupees in fees. So developers built Layer 2 solutions: networks that sit on top of Ethereum, bundle transactions together, and settle them on Ethereum for much lower costs.

• Polygon: An early Ethereum scaling network. Strictly, its main chain is a sidechain rather than a Layer 2, and its token was renamed from MATIC to POL in 2024.

• Arbitrum (ARB) and Optimism (OP): Layer 2s that settle their transactions on Ethereum, usually for a small fraction of Ethereum's fees.

Layer 2s are like express lanes on a highway: same destination, but faster and cheaper.

DeFi, Stablecoins, and Memecoins

Once the infrastructure existed, an entire ecosystem bloomed:

DeFi (Decentralised Finance): Apps like Aave and Uniswap let you lend, borrow, and swap crypto without intermediaries. High yields, but also high risk, because smart contract bugs have caused billion-dollar losses.

Stablecoins: Tokens pegged to real-world currencies. USDT, USDC, and DAI are all meant to stay at $1. Indian traders use them heavily because most trading pairs are in USDT.

Memecoins: Coins created as jokes that sometimes make people rich (and more often, make them poor). DOGE started as a Shiba Inu meme. SHIB, PEPE, and thousands of others followed. They have no technology behind them, so their value is pure speculation and community hype.

The Risk Spectrum

Here's the uncomfortable truth: most altcoins from any given cycle eventually lose most of their value.

A real example: In the 2021 bull market, Solana went from about ₹110 to about ₹19,000, roughly 170x. By late December 2022, it had crashed below ₹1,000 (down more than 95%). In the same period, Bitcoin went from ₹25 lakh to ₹50 lakh, then fell to about ₹13 lakh (down about 75% from its peak). The altcoin had more upside and far more downside.

BTC Dominance: The Market's Mood Ring

BTC Dominance measures what percentage of the total crypto market cap belongs to Bitcoin. It changes over time, and which way it is moving matters more than the level.

• BTC Dominance rising: Money is flowing into Bitcoin, away from altcoins. This usually means the market is cautious, because people want safety.

• BTC Dominance falling: Money is rotating into altcoins. This is what people call "altcoin season", when smaller coins start outperforming Bitcoin.

• A pattern from past cycles: Bitcoin often led first, then Ethereum, then smaller altcoins, and most of those later crashed. It is not a rule, and it has not played out the same way every time.

The Indian Tax Angle

The Indian government taxes all VDA gains at a flat 30%, whether it's Bitcoin or a random memecoin. There's no tax advantage to choosing one crypto over another. But the risk is dramatically different. A 30% fall needs a 43% rise to get back to where you started. A 95% fall needs a 20x rise, which most memecoins never make.

Quick Recap

• Bitcoin was first (2009) and remains the most established, liquid, and institutionally adopted crypto

• Ethereum introduced programmable blockchains, leading to dApps, DeFi, and the entire altcoin ecosystem

• Layer 2s solve Ethereum's scalability problems

• Altcoins offer higher potential returns but dramatically higher risk of total loss

• Most altcoins from any cycle lose most of their value

• BTC Dominance tells you whether money is flowing toward safety (Bitcoin) or risk (altcoins)

• In India, all crypto gains are taxed equally at 30%, but the risk profiles are very different
