BlackOps settles in one coin, Monero.
XMR
Why Monero only
Most markets take BTC and XMR and let you pick. BlackOps drops Bitcoin on purpose. Bitcoin sits on a public ledger and forensic firms trace exchange withdrawals to darknet spends all day. Monero hides the amount, the sender and the receiver at the protocol level, so there is no trail to follow. Running one private coin instead of one private and one public one is a deliberate stance, not a missing feature.
Deposit flow
Deposit addresses are made fresh for every order and never reused. Send from a wallet you control, not straight from an exchange that checked your ID. After the required confirmations, which for Monero works out to around twenty minutes, the balance credits. Withdrawals use the same fresh-address pattern.
