Two standout cryptocurrencies under $1, Shiba Inu (SHIB) and Lightchain AI (LCAI), are gaining attention as potential alternatives to Cardano (ADA) and Solana (SOL). LCAI, currently in presale at $0.003, integrates AI with blockchain through its Proof of Intelligence consensus mechanism, aiming for sustainable development. Meanwhile, SHIB, known as the "Dogecoin killer," has evolved from a meme coin to a community-driven project with legitimate use cases, including ShibaSwap for decentralized finance. Investors face a choice between SHIB's speculative growth and LCAI's technology-driven approach.
