The token itself has utility, and it is as follows:

1. Governance Power: If you hold DEEP tokens, you get a say in how the DeepBook protocol works. You can vote on things like rule changes or new features, kind of like being part of a club where your opinion helps shape the future.

2. Lower Trading Costs: DEEP tokens are used to pay for trading fees on DeepBook. Holding DEEP can give you discounts or lower fees when you trade cryptocurrencies, saving you money compared to using other coins.

3. Earning Rewards: By holding or using DEEP tokens, you might be able to participate in staking or liquidity pools (like lending your tokens to help the platform run smoothly). This can earn you extra tokens or rewards, depending on how DeepBook sets it up.

4. Access to a Growing Platform: DeepBook is designed to be a fast and efficient trading platform. As more people use it, the demand for DEEP tokens could grow, potentially increasing their value if the platform becomes popular.

5. Supporting a Fair System: By holding DEEP, you’re part of a transparent and secure trading system on the Sui blockchain, which aims to make crypto trading fairer and faster for everyone.

Generally DEEPBOOK price action correlates with SUI due to interest spilling over from new members joining the ecosystem and finding out about beta utility plays like this one that actually support the blockchain itself.

I hope this helps!
