Tell me if I have unluck on the project? why did I receive a letter about kyc and why should I go through it?

Do you mean you unlocked Pols and still received email on KYC?

When u got mail mate?

Your status can change after a while, it's best to apply for KYC if you get the link via email from this email id: tt@f-systems.xyz More details here

no, DEFY project - UNLUCKY, but i received email - DEFY Polkastarter Whitelist Winners - Please do KYC ASAP. It is SPAM?

Please read my above message, your status can change from unlucky as well
