Fund an order cleanly.
Mars issues a fresh deposit address per order.
Hold your own coin in Feather or Cake for Monero, or Sparrow or Electrum for Bitcoin and Litecoin, rather than sending straight from an identity-checked exchange.
Open the order, copy the deposit address, send from your wallet, and wait for confirmations. Keep the on-market balance sized to the order in front of you.
