Let’s imagine you would like to tap into news sources to analyze the events happening in Bitcoin or any in other topic area that frequently changes by the hour. These events could be analyzed to summarize the key changes or movements in Bitcoin, rate the overall sentiment of the recent discussions, capture important events, and so on. So you need a collection of recent Bitcoin events or news scraped every hour so that you can analyze these events.
