Payment and coins

Bitcoin, Litecoin and Monero. That spread is deliberate and it covers three different reasons a buyer picks a coin. Monero is the privacy default, the one to use when the reason you are on Tor at all is that you do not want the payment legible on a public chain. Its ledger hides amounts and parties by design.

Litecoin is the small-order coin. Bitcoin fees can make a modest purchase absurd, and Litecoin settles faster and cheaper for the times the number is small and you do not want to overpay the network for the privilege. Bitcoin sits in the list because a share of vendors still price in it and have not moved on.

Deposit addresses are issued per order. Fund the escrow, and the coin sits in the multisig contract until the order closes. The practical rule is the same across the atlas: keep the balance on the market sized to the order in front of you, not the year of orders behind you.
