You need to keep track of all the coin you invest. So use an application or a portfolio management website.

However, it is always the default that all of these applications / websites are dangerous. As a result, you are not allowed to provide any personal information for these applications, nor can you save or enter a wallet address in the application.

Users only need to enter the number of coin you own so that these applications automatically calculate the USD at current prices.
