Conclusion

Arbitrum confronts centralization critiques and technical bottlenecks while laying groundwork for safer, more decentralized operations. With stablecoin liquidity holding at $6.6B and DAO treasury reforms progressing, will 2026 see ARB decouple from Layer 2 growing pains into a governance premium phase?

What are people saying about ARB?

TLDR

Arbitrum's community debates whether $0.19 support can fuel a rebound or if macro downtrends will prevail. Here’s what’s trending:

  1. Bullish TA setups – Analysts eye $0.23–$0.40 targets on oversold bounce signals

  2. Bearish structure – Long-term chart shows ARB stuck below descending resistance

  3. Ecosystem strength – High network activity contrasts with weak token performance

Deep Dive

1. @bpaynews: Targeting $0.24 recovery bullish

"ARB shows bullish MACD divergence from $0.19 support... targeting $0.23–$0.40 over 4-6 weeks"
– @bpaynews (2K followers · 12.5K impressions · 2025-12-31 08:42 UTC)
View original post
What this means: This is bullish for ARB because MACD bullish crossovers historically precede 20-30% rallies when paired with oversold RSI (currently 44.17).

2. @MarkTheApe99: Macro downtrend intact bearish

"ARB's chart shows clear downtrend – needs break above $0.49 to reset structure... fundamentals ≠ price action"
– @MarkTheApe99 (4.2K followers · 8.7K impressions · 2025-12-27 14:23 UTC)
View original post
What this means: This is bearish as 87% of circulating supply remains locked with early investors, creating constant sell pressure during unlocks.

3. @Yashashre1: $5–$6 by 2031? mixed

"ARB's weekly chart suggests $2+ breakout potential... Timeboost's $6M cash flow proves real chain demand"
– @Yashashre1 (4.1K followers · 3.8K impressions · 2025-12-28 04:05 UTC)
View original post
What this means: Neutral long-term – strong network usage (211K daily users) supports fundamentals, but token economics remain inflationary with 57% circulating supply.

Conclusion

The consensus on ARB is mixed – technical traders see short-term rebound potential against persistent macro bearishness. Watch the $0.23 resistance level (23.6% Fib retracement) for confirmation of bullish momentum. Network growth metrics like daily transactions (349K) could eventually outweigh tokenomics concerns, but price discovery above $0.40 remains critical for trend reversal.

What is the latest update in ARB’s codebase?

TLDR

Arbitrum’s codebase recently introduced upgrades aligning with Ethereum’s Fusaka hard fork while adding Layer 3-focused features.

  1. Fusaka Upgrade (December 2025) – Enabled Ethereum EIPs, new opcodes, and gas optimizations.
