Hi @oguzhangazi
If you want to join the Crypto Class Action Knights Arise tournament you should sign up to the Crypto Class action to get your free SUFB token.
Just send an encrypted Steem memo to @jpbliberty saying "Join Crypto Class Action. My contact details are [email/Telegram/Discord]"
More details in this post. https://steempeak.com/fundition-iqx614ch7/@jpbliberty/one-click-crypto-class-action-signup-for-steemians
