Types of Crypto Assets

Not All Crypto Is Bitcoin

When most people hear "crypto," they think Bitcoin. But Bitcoin is just one of thousands of different crypto assets, and they're not all trying to do the same thing.

Think of it like the stock market. You wouldn't say "stocks" and mean only Reliance. There are tech stocks, bank stocks, small-caps, bonds, commodities, each with different risk profiles and purposes. Crypto works the same way.

Understanding the different types of crypto assets is essential because it determines how risky your investment is, what you're actually buying, and whether it has any real use beyond speculation.

How We Got Here: The Evolution of Crypto

To understand why there are thousands of crypto assets, you need to understand how we got from "one coin" to "an entire ecosystem."

2009: Bitcoin arrives. For years, Bitcoin was the only cryptocurrency. It did one thing: let people send digital money to each other without a bank. It proved the concept worked.

2015: Ethereum changes everything. Vitalik Buterin launched Ethereum with a radical idea: what if a blockchain could run programs, not just track payments? Bitcoin was like a calculator: it does one thing well. Ethereum was like a smartphone, and you could build apps on it.

These apps, called dApps (decentralised apps), opened the floodgates. Suddenly developers could build lending platforms, token exchanges, games, and digital art marketplaces, all running on Ethereum's blockchain without any company controlling them.

2017–2020: The Layer 1 race. As Ethereum got popular, it got congested and expensive. At busy times, a single transaction could cost thousands of rupees in fees. So other teams built competing blockchains: Solana (fast and cheap), BNB Chain (an exchange-backed ecosystem), Cardano (academic approach). These are all "Layer 1s": independent blockchains with their own infrastructure.

2021: Layer 2s, DeFi, and memecoins explode. To fix Ethereum's congestion, developers built Layer 2 solutions (such as Arbitrum and Optimism), networks that sit on top of Ethereum and process transactions cheaper. Meanwhile, DeFi apps let people lend and borrow without banks. NFTs let artists sell digital art. And memecoins (DOGE, SHIB) proved that internet culture could move billions of dollars.

2022–present: The ecosystem matures. Many projects from the boom died. The strong ones survived and grew. Today's crypto landscape is a full financial ecosystem: infrastructure, apps, money, and yes, plenty of speculation.

The Main Categories

Layer 1 Coins: The Infrastructure

These are cryptocurrencies that run their own blockchain. They're the foundation everything else is built on.

• Bitcoin (BTC): Digital gold. Store of value. The original.

• Ethereum (ETH): A programmable blockchain, so apps, contracts, and tokens can be built on it.

• Solana (SOL), BNB, Cardano (ADA): Alternative Layer 1s, each with different trade-offs in speed, cost, and decentralisation.

Layer 1 coins are like the land in a city: everything else (buildings, shops, roads) is built on top of them.

Tokens: Built on Someone Else's Land

Tokens don't have their own blockchain. They're created on existing ones, mostly Ethereum.

• UNI (Uniswap's governance token) runs on Ethereum

• LINK (Chainlink) runs on Ethereum

• Even USDT (Tether) runs on Ethereum, Tron, and other chains

The key difference: coins pay for their own network's fees. Tokens use someone else's network (and pay fees in that network's coin). When you send a token on Ethereum, you pay the fee in ETH, not in the token itself.

Stablecoins: The Bridge Between Crypto and Rupees

Stablecoins are designed to maintain a 1:1 peg with a real-world currency, usually the US dollar. The main ones you'll encounter:

Why Indians use them:

• Trading pairs: Most crypto trading happens in USDT, not INR

• Dollar exposure: Holding USDT gives you indirect USD exposure without needing a US bank account

• Moving between exchanges: Move USDT between platforms without going through your bank

But stablecoins carry real risks:

• USDT has repeatedly faced questions about whether Tether truly holds $1 in reserves for every token. Audits have been incomplete, and the company has been fined by US regulators.

• USDC temporarily lost its peg in March 2023 when Silicon Valley Bank collapsed: Circle had $3.3 billion stuck in the bank. USDC dropped to $0.87 before recovering.

• UST (an algorithmic stablecoin by Terra/Luna) lost its peg in May 2022 and collapsed within days, taking its sister token LUNA down with it; together they lost around $40 billion. It wasn't backed by real dollars. It relied on a code mechanism that broke under pressure.

The lesson: never keep all your stablecoin holdings in just one stablecoin. If you're holding a significant amount, split it across more than one stablecoin, for example USDT and USDC. This way, even if one stablecoin has a crisis, you don't lose everything.

Coins vs Tokens: A Quick Comparison

The Riskier Categories

DeFi Tokens: Governance tokens for decentralised finance protocols (lending, trading, staking). Examples: AAVE, COMP, UNI. These are speculative and their value depends on the protocol's usage and fees.

NFTs (Non-Fungible Tokens): Unique digital items (art, collectibles, game items). Each NFT is one-of-a-kind, unlike BTC where every bitcoin is identical. Important reality check: most NFTs from the 2021 boom are now worth a small fraction of what buyers paid.

Memecoins: DOGE, SHIB, PEPE. Created as jokes, driven entirely by community hype. Some people have made fortunes; far more have lost everything. These are essentially lottery tickets.

Quick Recap

• Crypto evolved from just Bitcoin (2009) to an entire ecosystem of Layer 1s, tokens, DeFi, and more.

• Layer 1 coins (BTC, ETH, SOL) are the foundation, they run their own blockchains.

• Tokens (UNI, LINK) are built on existing blockchains.

• Stablecoins (USDT, USDC, DAI) are pegged to the dollar but carry their own risks, so diversify across multiple stablecoins

• Memecoins and NFTs are the highest risk, so treat them as lottery tickets, not investments.
