The article introduces a new web app called Coin Exit Tracker designed to help crypto investors visualize potential profits at different exit points ranging from 1x to 25x. Users can input their coin, purchase price, quantity, and preferred currency to see target prices, total value, profit percentages, and progress bars. The app also features a Custom Sell Calculator to determine gains or losses from selling coins at the current price. It was built using React, Node.js, and CoinGecko API, with hosting on Netlify and Render. The creator was inspired by investor conversations and developed the app over Easter weekend, finding it to be a satisfying project.
