In order to spend with your CoinZoom Crypto Debit card, you must choose which currency to draw from each time you use your card. You can change it on-the-fly in your app at any time. When your card is first activated, the default spend currency is USD if it has an available balance. Otherwise another currency with a balance in it will be automatically selected.
An available balance means that the funds can be withdrawn immediately. Please see this article for details.

Spend Wallet Tips
When you make a card transaction, CoinZoom will:
Sell enough coins from your Spend Wallet to cover the purchase in USD.
Process the sale as a market order (price may vary slightly).
Best Practices:
Select a coin with high trading volume (liquidity) for more stable pricing.
Remember: Low-liquidity coins may sell at unexpected prices.
CoinZoom adds a 10% sell limit to help reduce price swings, but this is not foolproof for illiquid coins.
