Not all cryptocurrencies have staking because staking requires a specific blockchain network architecture that supports the Proof-of-Stake (PoS network) consensus mechanism. PoS allows users to participate in the network by staking their coins instead of mining with computational power like in Proof-of-Work (PoW) systems. Cryptocurrencies that have staking typically prioritize energy efficiency, scalability, and network security, which PoS consensus can provide. It is a design choice made by cryptocurrency developers and communities to promote participation and incentivize holding coins for network support. Additionally, not all cryptocurrencies need staking as their specific use cases or goals may not align with this particular mechanism. Learn more about Proof of Work vs. Proof of Stake.
