VII. FAQ

Q1: What is the main difference between PUBLIC and ARB in terms of their core value proposition?

PUBLIC focuses on building the human layer of AI through a gig economy model, addressing AI's data shortage crisis while creating work opportunities, whereas ARB operates as a Layer 2 scaling solution for Ethereum, enabling cheaper and faster transactions. PUBLIC represents an emerging AI-driven data ecosystem launched in 2025, while ARB has been operational since 2023 as established blockchain infrastructure. The fundamental distinction lies in their market positioning: PUBLIC targets the intersection of AI and decentralized labor markets, while ARB addresses Ethereum's scalability challenges through technical infrastructure.

Q2: How do the trading volumes and liquidity compare between PUBLIC and ARB?

ARB demonstrates significantly higher liquidity with a 24-hour trading volume of $2,667,301.94, compared to PUBLIC's $43,711.36 as of January 31, 2026. This represents approximately a 61x difference in trading activity. The substantial liquidity gap indicates that ARB offers easier trade execution and potentially lower slippage for investors, while PUBLIC's limited volume may result in price volatility and execution challenges during market fluctuations. This liquidity differential is a critical consideration for investors evaluating position sizing and exit strategy planning.

Q3: Which token experienced a greater percentage decline from its all-time high?

PUBLIC declined from its peak of $0.08285 (August 15, 2025) to $0.01575 (January 30, 2026), representing approximately an 81% decrease. ARB experienced a decline from $2.39 (January 12, 2024) to approximately $0.1545, reflecting approximately a 93.5% decrease. While both tokens experienced substantial corrections, ARB's percentage decline was more significant. However, this comparison should be contextualized: ARB's peak occurred during the 2024 market cycle, while PUBLIC's peak followed shortly after its 2025 launch, suggesting different market dynamics influenced their respective price trajectories.

Q4: What portfolio allocation strategy is recommended for conservative versus aggressive investors?

Conservative investors should consider a 20% PUBLIC and 80% ARB allocation, reflecting ARB's higher trading volume, established market presence, and operational track record since 2023. Aggressive investors may opt for a 40% PUBLIC and 60% ARB allocation, allowing increased exposure to PUBLIC's growth potential in the emerging AI-driven gig economy sector while maintaining substantial allocation to ARB's more liquid market dynamics. These recommendations account for liquidity differences, development stage variations, and risk-return profiles. Both strategies should incorporate hedging instruments such as stablecoin allocations for volatility management and options strategies for downside protection.

Q5: What are the projected price ranges for PUBLIC and ARB in 2030?

For 2030, PUBLIC's baseline scenario projects a range of $0.0150 to $0.0272, with an optimistic scenario reaching $0.0244 to $0.0329. ARB's baseline scenario for 2030 projects $0.1587 to $0.2736, with an optimistic scenario of $0.1910 to $0.3475. The predicted average price for PUBLIC in 2030 is $0.025423732152, while ARB's predicted average price is $0.232884707055. These projections represent potential price changes of 59% for PUBLIC and 50% for ARB from 2026 levels. However, these forecasts should be viewed as speculative estimates subject to numerous variables including institutional adoption, ecosystem development, and broader market conditions.

Q6: What technical risks should investors consider when comparing PUBLIC and ARB?

PUBLIC, as a project launched in 2025, faces considerations related to network scalability, platform stability, and ecosystem maturation as adoption develops in the AI-driven gig economy sector. The limited trading volume of $43,711.36 indicates the project is in earlier stages of market adoption. ARB, operating as a Layer 2 solution since 2023, encounters technical considerations including network performance maintenance, security protocol implementation, and ongoing infrastructure development. Both platforms must navigate their respective technical challenges: PUBLIC must prove its AI data ecosystem model can scale effectively, while ARB must maintain competitive advantages in an increasingly crowded Layer 2 landscape with evolving fee structures and Layer 1 cost dynamics.

Q7: How does the current market sentiment affect investment decisions for PUBLIC versus ARB?

The Fear & Greed Index reading of 16 (Extreme Fear) as of January 31, 2026, indicates prevailing negative market sentiment that influences both tokens. However, the impact differs based on their characteristics: PUBLIC's limited liquidity ($43,711.36 trading volume) makes it more susceptible to sharp price movements during fear-driven market conditions, while ARB's higher liquidity ($2,667,301.94) provides more stability during volatile periods. For new investors, this extreme fear environment suggests prioritizing ARB's established liquidity and operational framework. Experienced investors might view the fearful sentiment as a potential accumulation opportunity, but should account for liquidity differences and maintain appropriate risk management protocols given both tokens' substantial declines from their respective all-time highs.

Q8: What regulatory considerations distinguish PUBLIC from ARB for investors?

PUBLIC's AI-focused gig economy model and ARB's Layer 2 infrastructure role may encounter distinct regulatory frameworks as jurisdictions develop policies addressing emerging technologies. PUBLIC's positioning at the intersection of AI, data ecosystems, and decentralized labor markets could face scrutiny related to data privacy, labor regulations, and AI governance frameworks that are still evolving globally. ARB, as a Layer 2 scaling solution integrated with Ethereum's infrastructure, may be subject to regulations concerning blockchain technology, financial services, and cryptocurrency transactions that have more established precedents. Investors should monitor regulatory developments in their respective jurisdictions and assess how different regulatory approaches to AI technologies versus blockchain infrastructure might affect each token's operational environment and market positioning.
