If your order fails, try again after a few moments—it may resolve automatically. If issues persist, contact customer support for assistance.
Why do I only see certain cryptocurrencies listed?

Maximizing Your Crypto Purchases
Using your cash balance efficiently can enhance your investment strategy. Consider setting up recurring buys or using limit orders during high volatility periods to average your entry price over time—a technique known as dollar-cost averaging (DCA).
Additionally, keeping funds in your cash balance allows you to act quickly when market opportunities arise without waiting for bank transfers or payment processing delays.
For users looking to diversify beyond major coins, remember that while Quick Buy supports top-tier assets, broader access is available through spot markets where you can trade altcoins with low spreads and high liquidity.
