🎣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. 🛠️
