Tiers represent different levels of identity verification of your LoCoins account. Due to regulatory requirements the volume of exchange deals has to be limited for anonymous users. 

Your account is assigned Tier 1 when you sign up; higher Tiers then allow you to place more/larger exchange deals. You can upgrade your account to Tier 2 by confirming your phone number and to Tier 3 by validating your personal details through our partner Safened.
