The account has two parts.
USD balance
It's the center of the account. Releases, Pix contributions and conversions to USD land here. Withdrawals via Pix and contributions with balance come from here.
Crypto wallets
Each coin has its own wallet: USDT, USDC, BTC, ETH, SOL, BNB, TRX and POL. The value in crypto remains crypto: it doesn't turn into dollars on its own.
Moving between the two
To go from crypto to USD, or from USD to crypto, use Conversion (see the conversion course).
Summary
- The USD balance is the center of the account.
- Crypto remains crypto until you convert it.
