Buy crypto with fiat

KYC is required if you want to buy crypto with fiat. If you choose not to complete KYC, all features will remain accessible except buying or selling crypto for fiat.

Some other features also require KYC, such as accessing stocks and selling crypto for fiat. Once you complete KYC with Mass, you unlock all these features at once — no need to complete separate KYC processes for each one.
