HODL represents a community-driven meme coin project with utility for crypto enthusiasts. Several iterations exist, including fair launches and presales focused on the joy of holding (HODLing) crypto. Some versions feature no private sale, KYC verification, and audits, alongside social media platforms and prize pools. Others offer DeFi environments with swap, stake, farm, and bridge functionalities for ETH and BTC, along with CEX listings, CMC fast track, and AI-enhanced applications. The core principle revolves around camaraderie and rewards for long-term holding, with some projects emphasizing no team tokens or tax fees.
