This was the exchange bought by another blockchain project called Lala World right?
1. Earn daily income in the form of COS or ETH paid based on the profit the exchange makes daily (Imagine earning a portion of BNB's profits daily! COS has huge long term potential)
Is there a minimum number of tokens to hold inorder to qualify for this? Is KYC also needed here to withdraw those earned income from holding?
No minimum number of tokens needed and KYC is not required to withdraw anything less than 2 BTC per day. So unless you're buying like a million COSS or something you should be able to withdraw your daily earnings without any issue.
