Steps to  gain karma points on Reddit quickly:

• First, make a good point and then make a comment.-Another smart strategy is to keep an eye on new posts in popular subreddits and jump on the ones that have a high chance of being upvoted. By virtue of proximity, if the post becomes popular, your comment will rise with it. However, just because it's the first one doesn't mean it'll get more votes. Insightful, well-thought-out explanations and arguments, as well as witty remarks and pertinent GIF reactions, are usually good material for upvotes.
• Use r/AskReddit to ask and answer questions.- r/AskReddit, one of the most popular subreddits, with over 33.6 million subscribers. The principle is straightforward and enticing: ask questions and provide answers.
• Almost anything is acceptable here. If enough people think your query is worthwhile, your Karma will likely increase by thousands of points.
