Choosing what to carry
Bitcoin, Litecoin, Monero, Ethereum. Which coin for which crossing.
The coins accepted across this atlas are Monero, Bitcoin, Litecoin and, on one plate, Ethereum. Each answers a different question, and choosing well is part of crossing safely.
Monero, the privacy default
Monero hides the sender, the receiver and the amount by design. If the reason you are on Tor at all is that you do not want the payment legible afterward, Monero is the answer, and it is the coin to default to unless something forces otherwise. Most markets in the atlas now set it as the default themselves.
Bitcoin, the legacy coin
Bitcoin is the most widely held and the easiest to acquire, and it leaves the clearest public trail. Its ledger is fully readable. Use it when a vendor takes only Bitcoin. If you do, do not send straight from an identity-checked exchange to a market, because that ties your name to the deposit. Route through a fresh wallet or a swap first.
Litecoin, the small-order coin
Litecoin behaves like Bitcoin but settles faster and cheaper. It is the coin for small orders where Bitcoin's network fee would be out of proportion to the purchase. Two markets on the chart accept it.
Ethereum, the narrow case
One plate accepts Ethereum. Its chain is as public as Bitcoin's, so paying in it buys convenience when that is the coin you hold, not privacy. If privacy is the goal, the answer circles back to Monero every time.
