Primarily, the KYC level you are required to undertake is based on how much ETN you hold or use within a 3 month period. To summarise, level one is collecting your basic information, level two is submitting documents to prove you are the person you entered and level three is proving you have the financial means to source the funds you have used in your account under AML laws.
LEVEL 1 : 0 - 150€
Everyone must complete level one of KYC. This enables you to use/hold up to 150€ of ETN within a 3 month period.
LEVEL 2 : 150€ - 10,000€
Level two is required if you wish to use/hold over 150€ in a 3 month period (but up to a maximum of 10,000€).
LEVEL 3 : 10,000€ +
Level three is for those using/holding above 10,000€ (unlimited €) worth of ETN within a 3 month period.
