I think that KYC is all reason not to give you your coins earned honestly. I had experience with the company moneytoken, I participated in the bounty I credited coins in my personal account. I passed KYC documents accepted and approved positively. After some time, the company decided to take away from the personal cabinet. accusing me that I have a multi-account. I provided them with evidence that there was not any deception on my part and that I was doing the work in good faith. now the command is silent does not respond to my requests. I consider it a theft passing verification is useless.
They could be just using that excuse not to pay you, if ever you never had multiple accounts. That is the reason why I avoided ICOs that needs KYC because you never know what will happen to your personal information, especially if they never even paid you your dues.
