According to Flood (@ThinkingUSD) on Twitter, the primary challenge for crypto-based subscription models is the lack of automated recurring payments with crypto and stablecoins, which limits the success of such business models. Verified sources such as The Block and Decrypt confirm that while some projects like Mirror (decentralized publishing) and Unlock Protocol (membership NFTs) have seen moderate adoption, there is no clear market leader in successful crypto subscription-based businesses. Most solutions rely on manual renewals or complex smart contracts, which hinder mainstream adoption and scalability for traders and investors. This limitation continues to impact the development of recurring revenue streams in the crypto sector, affecting long-term investment strategies and project valuations.
