Make an easy experiment in 2025:
1. Ideal privacy: Anonymous cash (Monero, Bitcoin Lightning, Cashu)
2. Semi-ideal privacy: Pseudo-anonymous, decentralized crypto (Bitcoin, Ethereum, DAI, LUSD, etc.)
3. Less privacy & More centralization: Pseudo-anonymous, centralized crypto (USDT / USDC stablecoins).
Direct crypto payments require high crypto adoption and (ideally, non-KYC) crypto/fiat exchanges.
1. Ideal privacy: Cash (is the king)
2. Better privacy: Bank account and (crypto) payment cards from the financial institution in the non-CRS country (Paraguay, Kyrgyzstan, Cambodia)
3. Acceptable privacy: Bank account in (crypto payments) cards from the CRS country where it is possible to register your non-CRS tax residency (e.g., open your Bank of Georgia bank account or XAPO account with your Paraguayan Tax ID).
4. No privacy: Bank/fiat account in the CRS country (most countries including the EU), e.g., complete reporting of all transactions inside of Slovakia
Global by default (one wallet = entire planet, no IBAN's, no SWIFT codes)
Resistant to Censorship, Freezing
Cashu stands out as one of the implementations of Chaumian e-cash, alongside projects like Fedimint.
Cashu relies on mints, effectively Lightning nodes, to issue tokens representing Bitcoin holdings. These tokens enable anonymous transactions within the Mint's network.
The beauty of Cashu lies in its blinding mechanism, which ensures that even the mint operator is unaware of token ownership and transaction details.

We are not only experts on Paraguay, Uruguay, or Panama residencies but also have insight into the current global offshore infrastructure, especially for crypto enthusiasts.
