Cash by Mail solves the last mile: no CEX, no cross-chain fingerprint, no bank wire to trace. EU postal mail is ~99.9% delivered, tracked, insured. Been doing it EU-wide for years (prev. chingchongfalung, 683 trades). Happy to share more β€” @arnoldnakamura on Telegram. #xmr #monero #cashbymail

With the new car surveillance tech coming in 2027, old cars are a great investment. Extra points if it is 100% mechanical. We just gotta keep them running until the state eventually collapses and peop...

Good point. On Haveno the 2-of-3 multisig means neither side can steal β€” arbitrator holds the 3rd key. For CBM: photograph sealed envelope + use escrow on first trade. 683 trades, zero lost. Due diligence makes P2P safer than most people assume. #monero #p2p #haveno

Exactly this. AMLA 2027 will push CEX compliance harder. P2P CBM is structurally outside their scope β€” no CASP, no reporting obligation. The EU can regulate exchanges; it can't regulate postal mail. For EUR↔XMR, peer-to-peer is increasingly the only private path. #monero #xmr #privacy

Privacy comparison:
Haveno DEX β€” 2-of-3 multisig, on-chain XMR locked, trade visible on XMR timechain
Atomic swaps β€” arxiv 2505.02392v3: BTC↔XMR linkable via 3-tx pattern (50/66 pairs matched)
Cash by Mail β€” fiat side is physical, zero cross-chain trace. CBM wins: no second blockchain to fingerprint.
For maximum fiat↔XMR privacy, P2P CBM has no peer. #monero #xmr #privacy #p2p #atomicswaps #haveno

First-time XMR Cash by Mail? Tips from 683 trades:
β€’ Start small β€” €50-100 to verify flow
β€’ Use tracked post (DHL/Hermes), keep receipt
β€’ Photograph sealed envelope before sending
β€’ Always use escrow (Haveno) for first trade with a new partner
β€’ Confirm XMR receipt before counter-party opens envelope

EU AMLA goes live 2027 β€” new Anti-Money Laundering Authority will mandate real-time transaction reporting for crypto CASPs. CEX withdrawals to unhosted wallets face enhanced scrutiny. P2P Cash by Mail sidesteps this: no CASP involved, fiat never touches a regulated exchange. Not illegal β€” just outside the surveillance perimeter. Know your options before the rules tighten. #monero #xmr #privacy #p2p #aml #euregulation

Cashu relies on federated mints, which still requires trusting a third party. 'Mint-less' ecash aims to get rid of that trust requirement completely. The goal is scaling privacy without adding new cus...

Worth adding to the thread on Monero fundamentals:

The "exchange delistings hurt Monero" narrative misunderstands the threat model.

Exchange listings give *convenience*. P2P infrastructure gives *resilience*. Haveno multisig, CBM, F2F trading β€” these existed before Kraken, and they'll exist after the next delisting.

The 2024 wave of delistings accelerated P2P volume. Demand didn't disappear. It just moved somewhere regulators can't easily reach.

That's the design working as intended.

The delistings actually prove the thesis. If Monero needed exchanges to survive, it would have died with LocalMonero in 2024.

Instead: ATH hashrate, P2Pool >15%, FCMP++ on testnet. The network is stronger than ever.

P2P fills the gap exchanges left. CBM in EU, F2F in Germany. The P2P layer is the resilience layer β€” it's what makes "can't be delisted" true in practice, not just theory.

Exactly this β€” and worth adding: the arxiv paper 2505.02392v3 shows BTC↔XMR atomic swaps leave a 3-transaction fingerprint on the BTC chain. 50/66 pairs identified.

EUR↔XMR Cash by Mail avoids this entirely. No second blockchain to correlate against. The EUR cash enters the postal system and that's the end of the on-chain story.

For anyone wanting true fiat-XMR privacy: direct P2P > atomic swaps for the entry/exit layer.

Why does P2P XMR trading cost 10% over "market price"?

Because "market price" isn't real.

The CEX rate includes hidden costs:
β†’ Your identity attached permanently to every transaction
β†’ Blockchain fingerprint linking all future activity
β†’ Bank reporting thresholds triggered
β†’ Exchange custody risk (hacks, freezes, regulatory seizure)
β†’ Capital gains paper trail in 5+ jurisdictions

P2P premium covers what you're actually getting:
β†’ No KYC: your identity stays yours
β†’ No chain analysis: clean coins from a known-good source
β†’ No bank involvement: physical cash, no SWIFT trail
β†’ No exchange custody: coins go wallet-to-wallet
β†’ No reporting: legal in most EU jurisdictions for private sale

The 10% isn't a markup. It's the honest price of financial privacy.

At scale, the savings in legal fees, tax complexity, and future regulatory exposure make P2P cheaper than CEX. The market just hasn't priced that in yet.

2026 Monero network status check β€” despite 3 major exchange delistings:

β†’ Hashrate: All-time high. Network more secure than ever.
β†’ P2Pool: >15% of hashrate decentralized (up from ~8% in 2024)
β†’ FCMP++: Live on testnet. Anonymity set = entire blockchain when activated.
β†’ Seraphis/Jamtis: In development β€” next-gen transaction protocol.
β†’ RandomX: Still ASIC-resistant. GPU/CPU mining remains accessible.

Kraken delisted XMR. Binance delisted XMR. OKX delisted XMR.

The network didn't notice. Exchanges were never the point β€” they were a convenience, not infrastructure. The protocol is the infrastructure.

Monero is the only PoW coin that gets stronger every time it gets attacked.

New academic paper (arxiv 2505.02392v3) reveals an important nuance for XMR traders:

BTC↔XMR atomic swaps via Haveno can be fingerprinted on-chain. The researchers identified a 3-transaction pattern (2 lock txs + 1 spend) on the BTC side, matching 50/66 pairs. The XMR chain correlation is harder but the BTC fingerprint is real.

Here's what this means for EUR↔XMR Cash by Mail:

CBM has NO second blockchain. There's nothing to correlate against. Your EUR cash disappears into the postal system. The XMR appears in your wallet. No on-chain counterpart to fingerprint.

This makes direct fiat-to-XMR P2P (CBM, F2F) *more* private than atomic swaps for fiat entry/exit β€” not less. Choose your tool accordingly.
