This timeline walks through El Salvador's Bitcoin Law, the Chivo wallet, the IMF loan that made acceptance voluntary, and the 7,809 BTC the state holds, with every claim dated and sourced.
This guide explains what Taproot changed in November 2021, counts every input in eight October 2026 blocks to measure its real share, and sets out the proposals and fights that followed.
This guide shows how Bitcoin dominance is calculated, why three trackers read 57.50% to 60.18% on the same day, and what 2,754 rolling windows say about the falling-dominance altseason rule.
Bitcoin and Ethereum both sit atop crypto, but one is a fixed-supply money and the other a programmable platform. A dated, measured comparison: price, supply, security, volatility and what each bet needs to hold.
What is Stacks? A separate smart-contract chain with its own STX token that settles to Bitcoin. This guide covers sBTC, Bitcoin Staking and DeFi, and why STX sits 90% below its high.
BRC-20 and Runes both put fungible tokens on Bitcoin, but they differ in where the balance lives, how many transactions a transfer needs, and how far ORDI and DOG sit below their peaks.
Use this to read Bitcoin Ordinals at three levels: sat numbering and Taproot storage for builders, a measured inscription count for analysts, and October 2026 floor prices for collectors.
Use this to judge the Lightning Network before sending a sat: how channels and routing work, what 30,021 public channels hold, and which wallet type fits a payment.
Bitcoin keeps no account balances: a wallet's balance is a pile of separate coins, each spent whole and returned as change. This guide covers how that works, what it leaks about privacy, and why 164.6M of them sit in the UTXO set.
A 141-vB Bitcoin payment cost 141 sats, about $0.12, on 21 October 2026; in the April 2024 halving block the median fee was 200 sat/vB. This guide shows what sets the fee and how to cut it.
Use this to match a Bitcoin wallet to a need: native SegWit for cheap spending, multisig for large savings, self-custodial Lightning for small payments, a tested seed and passphrase backup for all of them.
This guide walks through every route to buy Bitcoin — exchange, app, ETF, Bitcoin ATM and peer to peer — with costs measured on 20 October 2026, ID rules for the US and EU, and the first withdrawal to a personal wallet.
Spot and futures bitcoin ETFs both put BTC exposure in a brokerage account — the difference is what the fund owns, what it costs to hold and how closely it tracks the price. Here is how each works and how to buy one.
Since 2015 Bitcoin has been four times as volatile as gold and fell 83% where gold's worst drop was 25%. It also tracked stocks slightly more than gold. A dated, measured test of the digital gold claim.
Roughly 600 sextillion hashes go into each Bitcoin block today, for a reward worth about $37 per petahash of hashrate per day. Here is how mining works, what it earns after the halving and what it costs in energy.
The published S2F formula implies about $55,000 after the 2020 halving and about $760,000 after 2024. Real prices came within 17% of the first and sat near a tenth of the second. Here is the test.
What is Bitcoin? A public ledger thousands of computers keep in sync, with a fixed issuance schedule and no company in charge. Here is how a payment confirms, how people hold BTC and what can go wrong.
Many traders buy when Bitcoin climbs above its 200-day average. We tested that rule on more than twelve years of prices: two out of three crosses fail within a month, and the four-year cycle explains far more.
Are launchpad tokens securities? On 31 August 2026 a New York federal judge held that the two tokens in front of her were not, on one narrow prong of the Howey test. The racketeering claims survived the same ruling.
