How to Buy Crypto
Buy Bitcoin, ETH, USDC, or USDT instantly in the Casa app using your Buy/Sell cash balance. Orders process instantly with email confirmation.
Before you buy, make sure you have cash in your Buy/Sell account. If you haven't deposited yet, see How to deposit cash via ACH or How to deposit via wire transfer.
Steps:
- Go to the Buy/Sell tab and tap "Buy."
- Choose the asset you want to buy. Bitcoin (BTC) is selected by default — you can also buy ETH, USDC, or USDT.
- Enter the amount.
- Tap "Review Order" to confirm the details
- Swipe to confirm your purchase. Most orders are processed instantly.
- You'll receive an email confirmation.

Important: Crypto purchased through “Buy/Sell” remains in your Zero Hash custodial account. For enhanced security, we strongly recommend transferring it to your Casa vault (or pay key) for self-custody protection.
