The referral system is 100% functional


If you are referring as a registered user, make sure to copy the link in the faucet page, the link must have your btc address and account id.

E.g. my referral link is https://btc2k.com/faucet.php?ref=1BcyZGp8EtE31fctjHhStnTV82M7ZjuKf7&id=1

If you are not registered, the &id= can be empty/isn't required, and payments will go to your unregistered wallet.
