This is a really easy to follow guide. All you need to do is pass KYC before sending in funds. To get your KYC approved it is very simple, upload a copy of your photo ID (e.g passport/drivers license) and take a selfie with your ID. You do not have to upload proof of address and it will only take a matter of hours to get approved by one of Natmin's team!
