$ADA . Development Speed vs. Quality
Proponents: Argue that Cardano's academic, peer-reviewed approach (led by IOHK and Charles Hoskinson) ensures long-term stability and security.
Critics: Say the project moves too slowly compared to competitors like Ethereum or Solana.
2. Smart Contracts and dApp Ecosystem
Debate: Is Cardano competitive in decentralized applications?
Challenge: Plutus and Haskell (its contract language) are seen as powerful but difficult for developers unfamiliar with functional programming.
