Transcribed Image Text:For this project, we are going to create an app that keeps an eye on the Bitcoin price -via the BitMex exchange. The app will contact the exchange every two seconds to obtain the latest Bitcoin price. It must compare the latest Bitcoin price with the previously obtained price (obtained two seconds before) and display it in a specific colour, depending on whether the price moved up, down or stayed unchanged. The app must also sound an alarm if the price moves above or below any of the userentered price levels. During each week, we will do a predetermined section of the required work-called a Sprint in Agile Development (a specific project management style used extensively in many IT development projects). In this first sprint, we will enable the user to add and remove price levels to the levelslist.
