Startup Idea: Investment Tracking Software for Stocks/Cryptocurrencies

Startup idea to develop a user-friendly software that helps new investors to efficiently track their stock and cryptocurrency purchases and sales. Aimed at simplifying tax filing processes and improving portfolio management.

I am a new investor in stocks/cryptocurrencies and was trying to figure to a good way to keep track of all of the purchases/sells. I have tried using excel but can't seem to find a good way to mend everything together. It is important to track all of these purchases to complete the proper tax filings. I have used excel to trying and make a comprehendible spreadsheet.
