A dollar buy-sell website allows users to exchange currencies, specifically buying and selling US dollars. These websites typically use scripts, which are sets of code, to handle tasks like:
- Calculating exchange rates: The script fetches live exchange rates or uses pre-defined rates to determine how much one currency is worth in another.
- Processing transactions: The script facilitates buy and sell orders, calculating the amount to be exchanged and ensuring sufficient funds are available.
- Managing user accounts: The script allows users to register, login, and manage their account information.
