Dev, you should tell your bounty participants not to post their application here in your ANN thread. You have a dedicated bounty thread, so post their info on that thread. Also, the certificates that you posted on your site is not a cryptoexchange license certificate. Are you in the process of acquiring your cryptoexchange license? Also, do you require KYC from your traders?
The certificates belong to Thisoption binary exchange.
KYC is required.
