# Fisherman NFT

* **Price:** **5 TON** per Fisherman.
* **Rarities / Levels:** 5 levels (Novice → Legendary). Each level differs in daily yield and ROI. 🌟
* **ROI:** 10–25 days depending on level (higher levels = lower ROI days). ⏱️
* **Profit (example model):** 25% – 150% total profit across lifetime (configurable per level). 💹
* **Expiration / Lifetime:** Each Fisherman has a finite lifetime (days), after which it stops producing unless renewed or replaced. This encourages reinvestment and active economy cycles. 🔄
* **Utility:** Fishermen are the primary TON generators and the main factor in bait/fish drop chance. Higher-level fishermen increase both yield and the probability of obtaining rarer fish. 🎯

**Design Rationale:** Time-limited Fishermen balance high short-term return with re-purchase demand — encouraging continual participation without permanent infinite income sources. 🛠️

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://tonfishisland.gitbook.io/whitepaper/gameplay-mechanics/fisherman-nft.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
