I really wish to participate in the trading competition but the KYC procedure make's its impossible for me No offense to your company but its too early to implement a KYC specially your just starting out and this is just a test trading account.
Maybe you could bend the rules for this competition and accept those users that wanting to join but cannot comply with your KYC requirements.
