**Crypto Cards Set to Stay Relevant in 2024 with New Tech and Features**

The cryptocurrency industry continues to innovate with new payment cards offering benefits like cashback and interest. Sergej Kotliar, CEO of Bitrefill, believes crypto cards will remain essential in 2024, enabling users to spend digital assets like Bitcoin and Ether as fiat currency. This helps save on exchange fees and combat inflation.

Key advancements include integrating the Lightning Network for faster, cheaper transactions, enhanced security, and broader merchant acceptance. Self-custodial wallets are also gaining traction, allowing users to store and spend crypto without third-party reliance. However, regulatory compliance and security concerns remain significant challenges.
