# Introduction

> Buy USDT with ARS, hold balances, and withdraw—on your schedule

## What you’ll accomplish

These guides explain how to use **Exchange** on HG.cash—the place where you turn **ARS into USDT**, keep **USDT in your accounts**, and move funds out when you need to.

Here’s what you can do:

* **Buy USDT with ARS** using the **Exchange** flows: pick the rate on screen (“spot”), pay from your **ARS** accounts, and receive **USDT** into your HG.cash balances.
* **Hold USDT on the platform** in your HG.cash **USDT** accounts until you withdraw or reuse the balance.
* **Create withdrawals** only to withdrawal wallets you register, sign, and that the team approves—your funds stay under controls you recognize.
* **Request a withdrawal 24/7** whenever you submit a valid withdrawal request in the product; timelines for review and on-chain payout follow the statuses and rules shown in the app and described in each guide below.

## Before you begin

* **Access**: Exchange (USDT) must be **enabled for your account**. If you do not see **Exchange** in the sidebar or you see “no access,” contact support.
* **Support**: Rejected wallets, spot schedule limits, unsupported countries for your ARS flows, or email rejected during signing require **support**—those outcomes are resolved with the team, not by changing settings yourself in these guides.
