Bithumb Suspends Arbitrum Network Deposits Amid Market Fear: Daily Crypto Analysis

VADODARA, January 5, 2026 — South Korean cryptocurrency exchange Bithumb will temporarily suspend deposits and withdrawals for 12 assets on the Arbitrum network beginning January 8, 2026, at 9:00 a.m. UTC, according to an official exchange announcement. This daily crypto analysis examines the technical implications of this network maintenance event within the broader context of global market fear and historical Layer-2 upgrade patterns.

Market Context & Background

Market structure suggests network upgrade suspensions often create temporary liquidity vacuums that can exacerbate existing volatility. Similar to the 2021 correction when multiple exchanges paused Solana network operations during congestion events, these technical pauses frequently precede short-term price dislocations. According to on-chain data from Glassnode, Layer-2 networks like Arbitrum have experienced increased transaction volume concentration during upgrade periods, creating order blocks that institutional traders monitor for entry opportunities. The current global crypto fear index at 26/100 indicates retail capitulation levels reminiscent of Q3 2022, potentially magnifying the impact of this technical event.

Related developments in the current market environment include Binance recording $2.4 billion in BTC and ETH inflows despite weakening whale demand and Bitcoin perpetual futures showing neutral funding ratios amid prevailing market fear.

What Happened?

Bithumb's official statement, as reported by primary source Coinness, indicates the suspension affects 12 specific assets on the Arbitrum network: ARB, GMX, ZTX, AGIC, XAI, ZRO, BOUNTY, ANIME, OBT, MLK, ETH, and LZM. The exchange cited "support for an upcoming network upgrade" as the rationale, with operations scheduled to resume following completion of the technical maintenance. This follows standard protocol for Layer-2 scaling solutions, where exchanges temporarily pause transactions to ensure wallet compatibility with new protocol implementations. Historical data from Ethereum.org documentation shows similar upgrade preparations typically last 2-4 hours, though exchange announcements conservatively estimate longer windows.

Technical Analysis & Price Action

Volume profile analysis indicates ARB has established a fair value gap between $1.55 and $1.62 following its November rally. The suspension creates a potential liquidity grab scenario where market makers may test the 50-day exponential moving average at $1.48 before the January 8 event. Market structure suggests the Bullish Invalidation level sits at ARB's 200-day simple moving average of $1.38, while the Bearish Invalidation level is the recent swing high at $1.78. For ETH, the critical Fibonacci support at $82,000 (38.2% retracement from all-time highs) represents a key technical level that could be tested during the suspension period.

By The Numbers

Why It Matters

For institutional participants, this event represents a controlled stress test of Arbitrum's network resilience during upgrade cycles. The concentration of 12 assets—including major DeFi tokens like GMX and the network's native ARB—creates a microcosm for observing cross-asset correlation during technical events. Retail traders face reduced arbitrage opportunities between Bithumb and other Korean exchanges during the suspension window, potentially widening bid-ask spreads. According to on-chain data from Etherscan, similar network upgrade pauses have historically resulted in 3-7% price volatility in the affected assets during the 24 hours surrounding the event.

Community Sentiment

Market analysts on X/Twitter have noted the timing coincides with broader market uncertainty. One quantitative trader observed, "Bithumb's Arbitrum suspension creates a natural experiment in isolated liquidity events—similar to the Binance Solana pause in 2021." Another analyst highlighted the technical aspect: "Watch for gamma squeeze potential in ARB options as the suspension reduces spot liquidity for delta hedging." The prevailing sentiment suggests most participants view this as routine maintenance rather than a fundamental concern.

Price Prediction / Future Outlook

Bullish Case: If the network upgrade implements expected EIP-4844 blob improvements for reduced transaction costs, ARB could reclaim the $1.70 resistance level within two weeks post-upgrade. Successful implementation would validate Arbitrum's technical roadmap and potentially trigger a relief rally toward the $2.00 psychological level.

Bearish Case: Should the suspension extend beyond the announced window or encounter technical issues, ARB could break below the $1.42 Fibonacci support, targeting the $1.30 volume gap from October. This would confirm a failed breakout structure and likely trigger stop-loss cascades in leveraged positions.
