Foundations
What is a Blockchain?
A blockchain is a database that's duplicated across thousands of computers simultaneously. Instead of one bank holding your transaction history, everyone in the network holds a copy — making it nearly impossible to alter records retroactively.
Foundations
What is Bitcoin?
Bitcoin was the first cryptocurrency — created in 2009 by an unknown person(s) using the pseudonym Satoshi Nakamoto. It introduced the idea of digital money that doesn't require a bank or government to function.
Wallets
Wallets: Custodial vs Non-Custodial
A custodial wallet is managed by an exchange — they hold your private keys. A non-custodial wallet means you control the keys directly. "Not your keys, not your coins" is the maxim. Both have tradeoffs worth understanding.

Custodial wallets (exchanges like Coinbase, Binance) are convenient but you're trusting a third party. If the exchange is hacked or collapses — as happened with FTX — you may lose everything. Non-custodial wallets (MetaMask, hardware wallets like Ledger) put you in full control but losing your seed phrase means permanent loss. For small amounts, custodial is fine. For significant holdings, self-custody is the standard recommendation.

Concepts
Market Cap Explained
Market capitalisation (market cap) = current price × circulating supply. It tells you the total value of all coins in circulation. A $50 coin with 1 billion coins has a larger market cap than a $5,000 coin with 100,000 coins.

Market cap is more useful than price alone for comparing assets. Bitcoin at $60,000 has a market cap of ~$1.2 trillion. A $0.01 token with 100 trillion supply has a $1 trillion market cap. Always check circulating supply. Fully Diluted Valuation (FDV) includes all future supply — if FDV is much higher than current market cap, significant inflation is coming.

Concepts
What are Altcoins?
Any cryptocurrency that isn't Bitcoin is an "altcoin". Ethereum, Solana, XRP and thousands of others are altcoins. They range from serious engineering projects to outright scams — due diligence is essential.
Security
How Scams Work
The most common crypto scams follow recognisable patterns: fake celebrity endorsements, "guaranteed returns", romance scams, phishing links, and fake token airdrops. Recognising them is your first line of defence.

Pig butchering: A scammer builds a romantic relationship over weeks before introducing a "great investment opportunity." Billions lost annually. Fake exchanges: Sites that let you deposit and show fake gains, then demand a "tax" before withdrawal. Phishing: Fake MetaMask/Ledger emails asking you to "verify your seed phrase." Rule: no legitimate service will ever ask for your seed phrase. Pump & dump: Influencers buy a low-cap coin, hype it publicly, then sell into the buyers. See enforcement actions →

Mining & Consensus
Proof of Work vs Proof of Stake
Proof of Work (Bitcoin) requires miners to solve computational puzzles — energy-intensive but battle-tested. Proof of Stake (Ethereum post-Merge) requires validators to lock up coins as collateral. Each has security and decentralisation tradeoffs.
Reading Charts
How to Read a Candlestick Chart
Each candle shows the open, close, high and low for a given time period. Green (or white) candles mean price closed higher than it opened. Red (or black) means lower. Wicks show the full high-low range. Volume bars below show how much traded.

The body of a candle is the open-to-close range. A long upper wick means buyers pushed price up but sellers brought it back down — bearish signal. A long lower wick means sellers pushed it down but buyers recovered it — bullish signal. Doji candles (tiny body) indicate indecision. Combine candlestick patterns with volume: a strong green candle on low volume is less meaningful than the same move on high volume. Try the HODL or FOLD game to practice reading live charts.

DeFi
How Liquidity Pools Work
Instead of a buyer and seller matching on an order book, DEXs use liquidity pools — pairs of tokens locked in smart contracts. Prices are set algorithmically by the ratio of assets in the pool. Providers earn fees but risk impermanent loss.
Stablecoins
Why Stablecoins Depeg
Fiat-backed stables depeg if the custodian's reserves are questioned (USDC depeg during SVB). Algorithmic stables can enter death spirals if confidence breaks (UST/LUNA collapse). Even over-collateralised stables can crack under extreme liquidations.
Tokenomics
Understanding Token Supply
Circulating supply is what's available now. Max supply is the hard cap that will ever exist. Fully diluted valuation (FDV) prices in all future supply. A low circulating supply with high FDV is a red flag — lots of inflation ahead.

Watch out for vesting schedules: if team and investor allocations unlock over 12-24 months, they will sell into your buying. Check the token unlock calendar — sites like Token Unlocks track this. A good tokenomic structure has a meaningful portion circulating at launch, not 2% with 98% held by insiders. Also check: is there a burn mechanism? Buyback programme? These affect long-term supply pressure. Use Blokaro's DCA calculator to model entry over time.

Security
Seed Phrases & Private Keys
Your 12 or 24-word seed phrase is the master key to your wallet. Anyone with it can take everything. Never enter it online, never photograph it, never store it digitally. Write it on paper, in multiple physical locations.

Your seed phrase generates your private key mathematically — it's not stored anywhere online. Best practices: write it on paper (or stamp it in metal for fire/water resistance), store copies in two separate physical locations, never in a photo, notes app, email draft, or cloud storage. Use a hardware wallet (Ledger, Trezor) for large holdings — these keep private keys offline. When setting up, verify you're on the genuine manufacturer's website. Fake hardware wallets have been sold with pre-loaded seed phrases.

On-Chain Analysis
Reading On-Chain Data
On-chain metrics — exchange inflows/outflows, HODL waves, realised cap, MVRV ratio — provide insight that price alone cannot. When long-term holders are distributing and exchange inflows spike, it often precedes corrections.
MEV
What is MEV (Maximal Extractable Value)?
Miners and validators can reorder, insert, or censor transactions to extract profit — called MEV. Sandwich attacks, frontrunning DEX trades, and liquidation bots all extract MEV. It's a multi-billion dollar shadow economy on Ethereum alone.
Layer 2
Rollups: Optimistic vs ZK
Rollups bundle many transactions off-chain and post compressed proofs to mainnet. Optimistic rollups assume transactions are valid unless challenged (7-day withdrawal delay). ZK rollups generate cryptographic proofs instantly but are computationally heavier.
Macro
The 4-Year Halving Cycle
Every ~4 years, Bitcoin's block reward halves. This reduces new supply entering the market. Historically, the 12–18 months following a halving have produced bull markets as demand meets reduced supply growth — though past performance is not predictive.
Regulation
How Crypto is Regulated in 2025
The EU's MiCA framework became the world's most comprehensive crypto regulation. The US continues operating via enforcement actions and unclear guidance. UK FCA requires marketing compliance. AML/KYC is now near-universal across exchanges.
Risk
Smart Contract Risk Explained
Smart contracts are code — and code has bugs. Audits reduce risk but don't eliminate it. The largest DeFi hacks have included reentrancy attacks, oracle manipulation, and flash loan exploits. Understand what you're putting money into.
📖
Quick Glossary
Essential terms defined without the hype
HODL
Originally a typo of "hold". The strategy of holding crypto long-term regardless of price volatility, without selling during dips.
FOMO
Fear Of Missing Out. The anxiety of watching others profit while you sit on the sidelines — often leads to buying at peaks.
FUD
Fear, Uncertainty and Doubt. Often used to describe negative news (real or fabricated) that suppresses a coin's price.
Whale
An entity holding a large enough position to move markets. On-chain wallets holding thousands of BTC are typically called whales.
Rug Pull
When developers abandon a project and abscond with investor funds. Common in new DeFi projects and meme coins.
ATH
All-Time High. The highest price a coin has ever reached. Often used as a reference point for drawdown calculations.
Gas
The fee paid to compensate network validators for processing transactions on Ethereum. Denominated in Gwei (nano-ETH).
Degen
Short for "degenerate". Refers to high-risk crypto participants who speculate on unproven projects for outsized returns.
Bridge
A protocol that allows assets to move between different blockchains. Bridges have been a major target for hacks.
Fork
A change to blockchain rules. Soft forks are backward-compatible; hard forks create a permanent divergence in the chain.
Airdrop
Free token distribution — usually to early users of a protocol or holders of a specific asset. Not all are valuable or safe.
GM / GN
"Good Morning" / "Good Night". Crypto Twitter greetings signalling bullish community engagement. Used earnestly and ironically.
Bag
A position in a particular coin. "Holding bags" often means being stuck with an investment that has declined significantly.
Mempool
The queue of unconfirmed transactions waiting to be included in the next block. MEV bots surveil it for profitable opportunities.
Slippage
The difference between the expected price of a trade and the executed price. Higher for large trades in illiquid pools.
TVL
Total Value Locked. The sum of all assets deposited in a DeFi protocol. A key metric for protocol health and adoption.
Multisig
A wallet requiring multiple private keys to authorise a transaction. A security standard for project treasuries and DAOs.
Tokenomics
The economic design of a token: supply schedule, distribution, vesting periods, utility, and inflation/deflation mechanics.
