ZIL, Zilliqa's cryptocurrency, is used for holding, transmitting, and staking and is utilized to maintain and operate the network.
Users obtain the capacity to vote on network enhancements by holding and staking ZIL, with each vote proportionate to the amount of ZIL they stake.
ZIL, like many other cryptocurrencies, has a finite supply, which means that there will only ever be 21 billion ZIL, according to the software's restrictions. So, Zilliqa seems real and safe to invest in.
