When comparing all these promising low-cost best crypto under $1—VeChain, Stellar, Kaspa, and Hedera—each has its own unique value proposition. They all offer something different, whether it's enterprise adoption, decentralized finance, technological innovation, or sustainability.

However, one project clearly stands out: BlockDAG (BDAG). With its ongoing record-setting presale, global adoption of its mobile mining app, and impressive infrastructure, BDAG is doing more than just making noise—it’s laying the foundation for exponential growth. With analysts already projecting a $1 target price post-mainnet launch in 2025, BDAG may offer the highest ROI of any crypto currently under $1.
