Binance does not have a product or feature called "protofile." However, it does offer robust portfolio management tools that are essential for traders and investors. The Binance portfolio feature, often found in the wallet "Overview" section, allows users to track and organize their investments across different cryptocurrencies. It provides a detailed view of asset allocation, real-time values, and performance trends over time.
For more advanced users, Binance offers tools like Portfolio Margin, which allows for a streamlined trading experience by using combined collateral across various products. Additionally, the platform provides analytical tools and reporting features to help users make informed investment decisions and manage risk effectively.
