Privacy tools for bitcoin users
These tools reduce the trail of personal data at each stage: connection, identity, buying, holding and moving bitcoin. Each one has a page explaining what it is, how to use it and its limits.
VPN
A VPN hides your IP from the site you visit and your traffic from your ISP; it does not make you anonymous to the VPN itself.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| Proton VPN · partner | Depends | to verify | See the site: there is a limited free plan and paid plans (Oct 2026) |
| Mullvad VPN | No | Yes | €5 per month, flat rate (Oct 2026); 10% discount when paying in crypto |
| IVPN | No | to verify | From US$ 60 per year on the Standard plan (Oct 2026) |
Browsers
The browser decides how much of your device each site can see: fingerprint, cookies and IP leaks.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| Tor Browser | No | to verify | Free (Oct 2026) |
| Mullvad Browser | No | Yes | Free (Oct 2026) |
| Brave | No | to verify | Free (Oct 2026) |
An email address separate from your name is the base for opening bitcoin accounts without tying everything to your main identity.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| Proton Mail · partner | No | to verify | Free plan available; paid plans from a few euros per month (check the site, Oct 2026) |
| Tuta · partner | No | to verify | Free plan available; paid plans from a few euros per month (check the site, Oct 2026) |
Email aliases
An alias is an address that forwards to your real inbox: one per service, disposable when it leaks.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| SimpleLogin | No | Yes | Free up to 10 aliases; Premium plan at US$ 36 per year (Oct 2026) |
| addy.io | No | Yes | Free plan available; check limits and prices on the site (Oct 2026) |
Passwords
A password manager lets you use a long, unique password for every account without memorising any but the main one.
Two-factor authentication
The second factor protects the account even when the password leaks; an app or hardware key is safer than SMS.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| Aegis Authenticator | No | Yes | Free (Oct 2026) |
| Ente Auth | No | Yes | Free (check the storage plan on the site, Oct 2026) |
Phone number
A mobile number is one of the strongest identifiers there is; a separate number for sign-ups weakens that link.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| Silent.link | No | to verify | Pay per GB of data, with a price that varies by region (check the site, Oct 2026) |
Messengers
P2P trades run over chat; the messenger decides who sees the content and the metadata.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| Signal | to verify | to verify | — |
| SimpleX Chat | to verify | to verify | — |
Directories and checks
Before depositing anywhere, check what the service really requires and whether your data has already leaked.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| KYCnot.me | No | to verify | Free (Oct 2026) |
| Have I Been Pwned | No | to verify | Free (Oct 2026) |
Hardware wallets
A hardware wallet keeps the keys off your phone and computer; it is where long-term savings belong.
Software wallets
Software wallets with coin control (UTXO) let you spend without merging coins from different sources.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| Sparrow Wallet | No | Yes | Free (Oct 2026) |
| Wasabi Wallet | No | to verify | Free; CoinJoin has fees set by the coordinator (Oct 2026) |

| Ashigaru | No | Yes | Free; 5% anti-Sybil fee on the pool size to join (Oct 2026) |
Swaps
A swap trades one coin for another; in atomic swaps nobody holds custody halfway through.
| Tool | KYC required | Open source | Price |
|---|---|---|---|
| eigenwallet | No | to verify | No subscription; funded by donations; swap terms depend on each liquidity provider (Oct 2026) |
| BasicSwap DEX | No | to verify | No trading fees, according to the project (Oct 2026) |
| Haveno | No | to verify | Varies by network (Oct 2026) |

Frequently asked questions
- Do I need every tool?
- No. Pick by threat model: someone who only wants to buy without exposing documents needs fewer layers than someone separating their identity entirely.
- Does any tool make bitcoin anonymous?
- No. Bitcoin is pseudonymous: these tools reduce the links between you and your coins, but none erases the public blockchain history.
