// The purpose of Kitty Club is to acknowledge all of the
// OG bad-asses who helped CK survive/grow during its infancy

// Without you, CK wouldn't be where it is today
// The CAT coin will be sent to community heroes, influential players, developers, etc
// Only 99 CAT coins will ever be minted

// You can not buy your way into the initial invitation of Kitty Club. You must be invited.
// Years in the future, we will know what path CK has taken. Assuming CK becomes a worldwide sensation,
// CAT coin could signify Kitty Club membership and may be required for entrance into exclusive yacht parties...who knows?

// Your initial invitation CAT coin is 100% yours. Feel free to sell it, gift it, send to 0x00
// Know that if you do any of these things, you will not be reinvited
// As of 11/11/2018, this is a silly project. If CK doesn't succeed, it will be an utterly meaningless token.
// If it does succeed however... See you in the Maldives ;)
