Reddit Premium: Reddit has a paid subscription which allows users to “support Reddit, get VIP treatment, exclusive access, and monthly coins.” Users have the option to pay $5.99 per month or $49.99 per year. With Premium, Redditors receive an ad-free experience, 700 free monthly coins, a personalized avatar (”snoovatar”) and access to r/lounge, an exclusive member-only subreddit. As of 2021, Reddit Premium is estimated to have roughly 350,000 paying users.
Coins: Redditors can purchase and gift these virtual goods to other users for their content and engagement. If a user wants to show appreciation for other users’ posts, comments, or live broadcasts, they can award coins to that user. These coins are typically paid for with real money. Users can gain r/lounge access with dollar payments or coins: 1,800 coins or $5.99 provides a month of access while a week of access costs 500 coins or $1.99.
