The website below claims to redeem your bitcoin diamon if you paste your 12 word seed. Not sure if this is legit or not.
http://bcdclaim.org/Anyone/anything that asks information about your bitcoin wallet password, private keys, 12-word seed or any sensitive information, is most likely a scammer, in this case that website is 100% a scam.
Do not share your wallet info, otherwise, you will lose your coins forever. You have been warned.
