Understand crypto before you touch it
Twenty guides written from primary sources — regulators, protocol documentation and public reports — with every figure dated and linked. No buy signals, no referral links, no return promises.
Start here
The six guides that cover what you need before buying your first fraction of a bitcoin.
Bitcoin vs Ethereum: the differences that actually matter
Bitcoin and Ethereum are not competing for the same job: monetary policy, consensus, what each really costs to use as of August 2026, and what you can build on top.
12 minProof of Work vs Proof of Stake: what each one actually protects
PoW pays for security with energy, PoS with confiscatable capital. How they work, what an attack would cost, and the real Bitcoin and Ethereum numbers in 2026.
13 minRegulationCrypto Regulation in 2026: MiCA, the United States and Latin America
MiCA title by title, the EMT/ART stablecoin regime and its transaction cap, the Binance exit, the GENIUS and CLARITY Acts, the SEC/CFTC token taxonomy and Latin American registers.
16 minInvestingCrypto Trading: The Concepts You Need Before Your First Order
Order books, slippage, order types, maker and taker, leverage and liquidation, with real 2026 fee schedules and the true annual cost of trading every day.
12 minSecurityCustodial vs non-custodial wallets: who actually holds your keys
The precise technical difference, what happened at Mt. Gox, FTX and Celsius, the $713M stolen from personal wallets in 2025, and what MiCA really protects.
13 minSecurityHow to choose a hardware wallet: the criteria that actually matter
Secure elements, open firmware, passphrases and threat models. Fifteen models compared with August 2026 prices, plus what really happened in Ledger's four incidents.
15 minHow we write this
Three rules that separate us from the noise.
Every figure, dated
Market data expires. Ours carries the collection date and a link to the original source so you can check it.
No money involved
We use no exchange or wallet-maker referral links. When we name a product it is because it is relevant, not because we are paid.
We say what we do not know
If a figure cannot be verified against a reliable source, we say so instead of filling the gap. Honesty about limits is part of the content.
