Getting Monero in without a thread
The deposit itself is easy. The part that matters is where the coin came from before it reached the market.
BlackOps hands each order its own deposit address. You send Monero to it, wait for the confirmations the market asks for, and the balance appears against that order. The mechanics are boring. The routing before it is where care pays off.
Do not send straight from an exchange
If you buy Monero on an identity-checked exchange and fire it directly at the market, you have drawn a line from your verified account to the deposit. Monero breaks the chain once it moves, but clean habit is to move the coin into a wallet you control first, let it settle, and send from there. Feather and Cake Wallet both do this well and both run over Tor.
Acquiring the coin
You can buy Monero on most large exchanges, or acquire it without an identity check through a peer trade or a swap from another coin you already hold. Whichever route, the goal is the same. The coins should sit in your own wallet before they go anywhere near an order.
The deposit, step by step
Open the order, copy the deposit address it shows, and send the exact amount from your wallet. Monero confirmations land in roughly twenty minutes. Keep the balance you hold on the market no larger than the order in front of you, and withdraw anything you are not about to spend. A market wallet is a place to pass through, not a place to store.
