Bitcoin analytics, explained.
Clear, no-fluff breakdowns of the indicators and on-chain metrics that drive btclyzer's BUY / SELL / HODL ratings. Written for traders who want to understand why a rating flipped, not just that it did.
Sentiment & cycle
Live nowBitcoin Fear & Greed Index, explained
The 0–100 score from Alternative.me — what it actually measures, how it's calculated, and how to use it without falling for the contrarian trap.
CBBI — Bitcoin Bull Run Index
The Colin Talks Crypto composite that aggregates 9 cycle signals — Pi Cycle, MVRV Z-Score, Puell Multiple, RHODL and more — into one 0–100 score.
Bitcoin mempool, explained
How the mempool works, sat/vB fee tiers, why congestion spikes during halvings and Ordinals rallies, and what mempool size tells you about live BTC demand.
Technical indicators
In productionRSI on Bitcoin — how to actually read it
RSI(14), the 30/70 thresholds, what divergences mean, and why "RSI over 70 means sell" is wrong most of the time.
MACD for Bitcoin traders
MACD line, signal line, histogram — what each one tells you and how btclyzer weights them differently on 1H vs 1D.
EMA 20 / 50 / 200 — the BTC trend triad
EMA vs SMA, why those three averages, what golden/death crosses actually mean for BTC, where the EMA ribbon helps vs misleads, and how btclyzer reads price-vs-EMA per timeframe.
On-chain metrics
In productionMVRV & MVRV Z-Score
Market value vs realized value — Bitcoin's aggregate cost basis, and the Z-Score whose extremes have marked every cycle top and bottom since 2013.
SOPR — Spent Output Profit Ratio
Are the coins moving on-chain today being sold in profit or at a loss? The SOPR = 1 pivot, the aSOPR / LTH / STH variants, and what they signal.
NUPL — Net Unrealized Profit/Loss
The network's paper profit as crowd psychology — capitulation to euphoria. Its link to MVRV, the cohort versions, and the zones that marked every turn.
The Puell Multiple
Miner revenue vs its yearly average — the forced sellers' cycle gauge. High = top-zone froth, low = miner capitulation. Plus the halving distortion.
History & origins
In productionSatoshi Nakamoto — the mystery
The 2008 white paper, the genesis block, the last message in 2011 — what we actually know about Bitcoin's anonymous creator, the ~1M BTC stash, and who he definitely wasn't.
Bitcoin halvings — 2012 to 2032
Four halvings down, the protocol rule that defines them, what each one did to price and miners, why the 2024 ETF-era halving distorted the cycle, and when block 1,050,000 lands.
The Bitcoin white paper, page by page
An annotated walk through the 9-page document Satoshi posted on a cryptography mailing list in October 2008 — every section, plain English, and what each idea set in motion.
Bitcoin safety
In productionNot your keys, not your bitcoin
Why the slogan exists, what an exchange balance actually is (a database row, not bitcoin), the failed-custodian history from Mt.Gox to FTX, and the decision matrix for self-custody vs exchange.
Seed phrase — backup that actually survives
BIP39 explained, 12 vs 24 words, the passphrase (25th word), paper vs steel backups, the six things you should never do with a seed, and a backup plan that survives fire, flood, theft and time.
Hardware wallets — Ledger, Trezor, Coldcard
How a hardware wallet actually protects you (signing offline, never exposing the seed), a side-by-side of the three big names, and how to verify a device hasn't been tampered with before you load funds.
