Coins, fees and refunds

Bitcoin is the default

Bitcoin is the primary currency across the whole interface. The settings allow a few alternative assets, but Bitcoin offers the deepest liquidity and the lowest slippage. Moving large sums in thinner coins often triggers higher spread costs because the order book is shallower. Stick with Bitcoin unless you specifically hold significant reserves in another asset.

Fees track network weight

There is no fixed service percentage baked into every purchase. The cost scales with current blockchain congestion, so during a spike even a small transfer carries a real mining cost. A deposit of under twenty dollars can effectively vanish if the fee rate spikes hard enough to eat the whole amount before it reaches the merchant. Small purchases are the ones to watch.

Refunds return to the source

Once an administrative ruling confirms the return, the funds flow back along the original path. The payout lands in the exact wallet address used for the initial payment, and there is no internal credit balance to manage afterwards. Everything moves in the same coin type you deposited, which keeps the records clean for both sides of the trade.

Keep your transaction hash

The single most reliable way to settle a refund quickly is to keep your records organised. Store the blockchain transaction hash alongside the internal order number in a plain text file. When a dispute arises, having those two strings paired lets the admin team verify your identity at once. Missing data turns a routine check into a forensic search.
