As 2021 comes to a close, Reddit has shared that cryptocurrency was its most viewed topic this year, beating out gaming, sports, and weddings, in that order.
The word “crypto” has been used over 6.6 million times across the site.
Perhaps the biggest surprise: Redditors were more interested in Dogecoin than Bitcoin. The top five most-viewed crypto subreddits were r/dogecoin, r/superstonk, r/cryptocurrency, r/amcstock, and r/bitcoin.
The most-upvoted crypto posts on Reddit this year were about DOGE, Tesla getting into Bitcoin, and crypto’s survivorship bias.

The massive financial subreddit r/wallstreetbets (WSB) also recently reversed course on its anti-crypto stance, allowing its 11.4 million members to discuss Bitcoin, Ethereum and Dogecoin in the subreddit earlier this year. In fact, WSB hosted an impressive rooftop soirée in Miami Beach during Art Basel, dubbed the “to the Moon NFT party,” a prime example of the subreddit’s ideological shift in 2021.

WallStreetBets (WSB), the Reddit forum that helped boost GameStop stock from the basement to the penthouse, is expanding its reach to cryptocurrency. The decision by moderators marks a reversal for the subreddit, which long felt that it would overpower the main mission of WSB: to discuss publicly traded stocks.

Redditors’ interest in cryptocurrency is longstanding, but 2021 was a year for the record books.

As cryptocurrency and NFTs went more mainstream than ever this year, crypto enthusiasts and newcomers alike took to Reddit to educate themselves and jump into the conversation.
