Yellow Token (YEL) started in 2017 and finished in 2018, with a total supply of 21 million tokens. The team/founder is hidden, The main reason this token was listed is desertion.

(from old site) Aside of the current events around airdrops we wanted to create something with value, instead of another senseless eXXX Token. As cryptocurrencies have always been driven by their communities, we wanted to take this back to the roots. Instead of a single developer, who can easily be overwhelmed by the success of a token, we are a team of five dedicated and experienced crypto enthusiasts. Our goal is to bring this token back to the roots: a cryptocurrency that rises and falls together with you - its community. Therefore we lay the future of this token into your hands by letting you decide all our future actions. In addition we will take part in other airdrops and hold the coins we receive from them in a fond. This fond will steadily increase the token value over time. With this approach we want you to look at this as your very own project that will be worth more and more in the future, because every single one of you will take a huge part in its development. Welcome to the Yellow Token family brothers and sisters.
