Monero XMR · Private digital cash — privacy by default, for everyone
Bitcoin BTC · The original — hardest money, transparent ledger
Bitcoin is the hardest money humanity has ever built — 17 years without a consensus-level theft, a $1.6 trillion market cap, US spot ETFs holding ~$100B, and a fixed 21 million supply every node can audit by summing coins. Monero does not beat that, and this page doesn't pretend it does: Bitcoin wins supply policy, adoption, security longevity and institutional access. What Monero wins is everything Bitcoin's transparent design forfeits: every Bitcoin payment is public forever, coins carry taint that exchanges act on, and the privacy tools that tried to fix it (Samourai, Wasabi's coordinator) ended in prosecutions and shutdowns. Two honest coins, two different bets.
Feature by feature
Privacy by default
Monero winsSender, receiver and amount hidden in every transaction by protocol — no option to get it wrong, no opt-in to forget.
Fully transparent ledger: sender, receiver and amount visible to anyone, industrialized by surveillance firms. CoinJoin exists but is opt-in, costs extra, and its coordinators were prosecuted or shut down (Samourai 2024, Wasabi's zkSNACKs 2024). Address reuse remains the default wallet behavior.
Fungibility
Monero winsNo coin carries visible history — every XMR is indistinguishable from every other.
Coins carry history: exchanges and analytics firms blacklist "tainted" BTC; OFAC has sanctioned Bitcoin addresses outright (Blender.io, 2022). A coin's past can reduce its acceptance — the definition of imperfect fungibility.
Confirmation speed
It depends2-minute blocks; merchants commonly credit at ~10 confirmations (~20 min) and funds re-spend at the same threshold.
10-minute blocks; 1 confirmation (~10 min) for retail, 6 (~60 min) for large settlement.
Fees
Monero winsMedian ≈ $0.01–0.05, stable and predictable — dynamic block size absorbs demand spikes instead of a bidding war.
Currently historically low: 1–2 sat/vB ≈ $0.11–0.22 for a typical transaction (Sep 2026). But the fee market is fat-tailed — the April 2024 Runes spike hit >1,300 sat/vB and ordinary users have paid $10–50 during congestion.
Throughput & scaling
It dependsDynamic block size (median penalty) gives the base layer headroom; a full node is ~250 GB, pruned ~55 GB.
~7 tx/s on-chain by design — Bitcoin scales by keeping L1 small (archival node ~760 GB) and pushing payments to Layer 2 (Lightning, covered on its own page).
Mining / validation decentralization
It dependsRandomX: any CPU mines — no ASIC market, P2Pool for decentralized pooling. Honest caveats: marginal profitability for home miners, and a much smaller security budget (~$87M/yr at current emission).
SHA-256 ASICs: industrial farms, ~922 EH/s, ~175–200 TWh/yr, a Bitmain/MicroBT hardware duopoly, and pool concentration (Foundry 24.9% + AntPool 19% + F2Pool 15.3% ≈ 59% top-3). In exchange: the largest security budget in history (~$15B/yr) and 17 years of never being 51%-attacked.
Supply policy
Competitor winsNo hard cap — 0.6 XMR/block tail emission forever (~0.84%/yr, monotonically falling). Auditable by summing coinbase outputs against the fixed rule — more work than Bitcoin's UTXO sum, and you verify the rule, not individual balances.
21M hard cap, halving every 210k blocks (next ~April 2028), and trivially auditable by every node. The cleanest monetary policy in existence.
Self-custody UX
It dependsWallets auto-generate stealth addresses — the single worst Bitcoin footgun (address reuse) doesn't exist. 25-word or Polyseed backups. Trade-offs: fewer hardware wallet options (Trezor dropped XMR in 2024), restore scans from block height.
The deepest custody ecosystem anywhere: every hardware wallet, BIP39 standards, PSBT flows — plus real footguns: address reuse, change-address confusion, UTXO management, fee sniping.
Adoption & liquidity
Competitor wins$10.4B mcap (#13), delisted from Binance/Kraken-EEA/OKX; acquiring XMR runs through DEXs, atomic swaps and instant exchangers.
$1.60T mcap (#1), US spot ETFs holding ~1.26M BTC (~$100B), ~27,000 mapped merchants, the deepest liquidity in crypto. No contest.
Censorship resistance
It dependsCoin-level immunity — an XMR output carries no history to blacklist. The asset itself, though, is censored at the exchange layer (delistings, EU CASP rules tightening toward 2027).
Protocol accepted by regulators — but coins are blacklisted (OFAC addresses), exchanges quarantine tainted BTC, and privacy-tool users face prosecution: Samourai's founders pleaded guilty in 2025 (4–5 year sentences).
Programmability
Competitor winsNone — payments only, by design (multisig exists).
Deliberately limited but real: Script, Taproot (2021, ~40–50% of outputs by 2025), and a live covenant debate (CTV, OP_CAT and friends) for 2026.
Security track record
Competitor winsTwelve years, no exploited protocol bug, no 51% attack — with the honest caveat of a far smaller security budget.
Seventeen years. Two consensus incidents ever — the 2010 overflow (fixed by Satoshi within hours) and CVE-2018-17144 (fixed before any exploitation) — no successful 51% attack, no consensus-layer theft, no undetected inflation. The longest clean record in the field.
Interoperability
It dependsThe richest no-KYC swap infrastructure in crypto grows around Monero: trustless BTC↔XMR atomic swaps since 2021, Haveno/Bisq DEXs, 200+ instant exchangers.
The deepest exchange, ETF and futures rails anywhere — every bridge, every wrapper, every venue. Getting BTC in and out of anything is trivial.
Governance & funding
It dependsNo foundation, no dev tax, no premine: CCS community crowdfunding, milestone-based. Capture-proof and chronically lean.
Also no dev tax or foundation control: Core developers funded through Brink, OpenSats, Spiral, HRF, Chaincode — dozens of independent sponsors, ~$8M+/yr. Distributed but institutionalized; maintainers still warn of a thin bench.
The honest scoreboard
BTC Where Bitcoin wins
- Supply policy — 21M hard cap, trivially auditable, vs tail emission
- Adoption & liquidity — $1.6T vs $10.4B; ETFs, merchants, institutional rails
- Security longevity — 17 years, two consensus bugs ever, neither exploited; ~$15B/yr security budget
- Institutional access — regulated spot ETFs holding ~$100B
- Base-layer verifiability — every satoshi auditable by every node
XMR Where Monero wins
- Privacy by default — every payment vs a permanently public ledger
- Fungibility — no taint, no OFAC-address blacklists
- Fee predictability — dynamic blocks vs fat-tailed fee spikes
- Mining accessibility — any CPU vs industrial ASICs
- A payments UX without address reuse built into the protocol
Common questions
Isn't Monero's tail emission "infinite supply"?
There is no hard cap — that's stated plainly. But the emission is a fixed 0.6 XMR per block, so the annual percentage falls forever (~0.84% now, ~0.5% by the mid-2030s), below credible estimates of natural coin loss. The design trades the cap for a permanent security budget — while Bitcoin's post-block-subsidy security depends on a fee market that delivered only ~0.6% of miner revenue in 2026. Two honest risks, pointed in different directions.
Can't you just use CoinJoin on Bitcoin for privacy?
You can — it's opt-in, costs extra fees, and the environment has turned hostile: Samourai's founders pleaded guilty in 2025, Wasabi's zkSNACKs coordinator shut down in 2024, and OFAC has sanctioned Bitcoin mixers. Monero's privacy isn't a service you request; it's the water every transaction swims in.

Is Monero's supply really auditable if amounts are hidden?
Yes, with an honest asterisk. Emission follows a public fixed rule and every coinbase is visible, so any node can verify total supply by summing them — you verify the rule rather than eyeballing balances, and range proofs mathematically prevent negative or inflated amounts. It's more work than Bitcoin's UTXO sum, and that difference is real. What has never been found, in 12 years, is evidence of inflation.

What was the IRS $625k Monero bounty about?
In 2020 the IRS paid up to $625k each to Chainalysis and Integra FEC to develop Monero (and Lightning) tracing. Six years later, no general-purpose Monero tracing tool has been demonstrated publicly; a leaked 2024 Chainalysis deck relied on running spy nodes to harvest IP metadata — defeated by running your own node over Tor — not on breaking the cryptography.
