Crypto Basics: Where Should a Beginner Start?
Nobody starts out knowing what a seed phrase is or why a swap on Ethereum L1 costs $18 while the same transaction on Base costs pennies. I didn't either. This page covers the minimum you need before touching real money.

Live Chain DataWhat Is Blockchain?
Blockchain is a shared record book that thousands of computers maintain at the same time. When you send Bitcoin or ETH, that transfer gets bundled into a block, cryptographically linked to the block before it, and broadcast to the network. Change one entry and the whole chain breaks— that's the point.
You don't need to read the whitepaper to use crypto. What you do need to know: there's no bank in the middle reversing charges, and you are responsible for keeping access to your funds. Lose your seed phrase, get REKT by a phishing site, send to the wrong address— nobody's calling support to fix it.
Bitcoin: The First Cryptocurrency
Bitcoin (BTC) launched in 2009. Fixed supply of 21 million. No CEO, no treasury department, no "we're pivoting to AI" earnings call. It's the asset most exchanges list first, the one institutions actually custody, and the benchmark everything else gets measured against.
Most people I know started with BTC not because it's the most exciting coin— it's not— but because it has 15+ years of uptime, deep liquidity, and you can explain what it does in one sentence: digital money with a hard cap.

Why L2 MattersAltcoins: Beyond Bitcoin
Everything that isn't BTC is an altcoin. Ethereum runs smart contracts— code that executes on-chain without a middleman. Solana, Avalanche, and the L2 networks (Arbitrum, Base, Optimism) compete on speed and fees. Smaller tokens might 10x or go to zero; there's rarely a middle ground.
- Large-cap altcoins — ETH, SOL, established L2 tokens with real usage and dev activity
- Mid- and small-cap tokens — higher upside, higher chance of getting REKT on a rug pull
- Stablecoins (USDC, USDT) — pegged to USD; useful for parking cash between trades, not a growth play

Reading about blockchain is step one. Step two is setting up a wallet that won't leak your seed phrase, figuring out whether you should HODL or DCA, and learning which scams are designed specifically to catch people who just arrived.

Do I need to buy a whole Bitcoin?
No. BTC is divisible to eight decimal places— you can buy $10 worth on any major exchange. Same goes for ETH and most altcoins. Nobody's gatekeeping you because you can't afford a full coin.
Is crypto just gambling?
Buying a random memecoin because an influencer shilled it? Yeah, that's gambling. DCA-ing into BTC and ETH with money you can afford to lock up for years, stored on a hardware wallet? That's closer to a high-risk savings strategy— still risky, but not the same thing as a casino bet.
What's the difference between an exchange and a wallet?
An exchange (Coinbase, Kraken, Binance) holds your crypto for you— convenient, but you're trusting them not to get hacked or freeze your account. A self-custody wallet (MetaMask, Trezor, Tangem) means you hold the keys. More responsibility, but nobody can lock you out except you.
