16. What is the impact of regulatory developments on the future of DEXs?

• They ensure DEXs operate exactly like centralized exchanges.
• They completely eliminate the need for user privacy in DEXs.
• They have no impact on the trading volume of DEXs.
• They influence the growth and adoption of DEXs by addressing regulatory uncertainty.

17. How do hybrid exchanges balance user-friendliness, compliance, and trading ecosystem?

• By using a completely centralized trading platform.
• By ignoring regulatory compliance entirely.
• By integrating the best features from both centralized and decentralized exchanges.
• By restricting access to a few select users.

18. What is the future direction for DEXs to ensure secure and user-friendly environments?

• By leveraging innovations like AMMs, cross-chain trading, and layer 2 solutions, and staying ahead of emerging trends such as DeFi, NFTs, and decentralized identity.
• By minimizing technological advancements and reducing the features offered to users for simplicity.
• By centralizing governance and focusing only on traditional trading methods to build user loyalty.
