Why coiners.club exists
A network you can only prove your way into.
Proven, not purchased
Every member proved at least one whole bitcoin: with a signature from their own wallet, or with a statement from their exchange that we checked by hand. Nobody gets in on a promise or an invitation.
As little data as possible
A member list of people who proved at least one bitcoin is a target list. That is why we keep your email address and your country, and throw away the addresses and balances you verify.
Offers worth your time
Partners give members deals, luxury, travel and events. They never receive your email address or country: offers reach you through codes or links from coiners.club.
What we never ask
If someone asks for this, it is not us.
- Your seed phrase or recovery words
- Your private keys
- To approve or sign a transaction
- To send bitcoin to an address
- Your name or an ID when you sign with your own wallet
To join you sign a one-time message with your wallet. Signing a message sends no transaction, so your bitcoin stays exactly where it is.
How to check us
Make sure you are dealing with us.
- Our only website is coiners.club. Check the address bar before you connect a wallet or sign anything.
- We never contact you first: not by email, not by phone and not in a direct message.
- In doubt about a message? Email [email protected] and we tell you whether it came from us.
What we keep about you, and for how long, is in the privacy statement.
