KYC (verification)
«Know Your Customer» — identity verification (documents) on exchanges and some services. Monitored exchangers often work without KYC for small amounts.
In more detail
KYC is identity verification by documents, mandatory on most exchanges and some services. Monitored exchangers often work without KYC for small amounts, which is convenient but does not remove responsibility for the origin of funds. For large operations verification may be required, so keep your documents handy.
