One of the best ways to keep track of your cryptocurrency holdings is by using a trusted cryptocurrency portfolio tracking app. Popular portfolio trackers such as BlockFolio and CoinTracking offer comprehensive tracking services that allow users to easily view their current holdings, monitor market prices, and get detailed reports about their portfolios. Additionally, there are many other tracking apps available for users to choose from. For example, Delta and Crypto Pro are two popular mobile-based portfolio trackers that allow users to keep track of their coins on the go.
