BitcoinWorld Bithumb FLOW Suspension: Essential Guide to the Crucial Mainnet Upgrade on January 29 In a significant operational update from Seoul, South Korea, on January 28, 2025, the prominent cryptocurrency exchange Bithumb announced a temporary suspension of all FLOW deposit and withdrawal services. This planned Bithumb FLOW suspension will commence precisely at 11:00 a.m. UTC on January 29 to facilitate a critical mainnet upgrade for the Flow blockchain. Consequently, this move highlights the ongoing evolution of blockchain infrastructure and its direct impact on user accessibility. Understanding the Bithumb FLOW Suspension Announcement Bithumb’s official notification provides clear details for its user base. The exchange will temporarily halt all deposit and withdrawal functions for the FLOW token. This action supports the underlying Flow blockchain’s scheduled network enhancement. Importantly, trading of FLOW tokens on Bithumb’s spot markets will remain fully operational during this period. Users can still buy, sell, and hold FLOW in their exchange wallets. The suspension specifically affects the movement of tokens onto and off of the Bithumb platform. This is a standard procedure for exchanges during major network upgrades to ensure transaction integrity and user fund security. The Driving Force: Flow Blockchain’s Mainnet Upgrade The core reason for this service pause is a scheduled mainnet upgrade for the Flow blockchain. Mainnet upgrades are essential software improvements deployed on a live blockchain network. They often introduce new features, enhance security protocols, improve scalability, and fix known bugs. For the Flow network, which is designed for next-generation applications, games, and digital assets, such upgrades are vital for maintaining performance and competitiveness. Exchanges like Bithumb must synchronize their systems with the upgraded blockchain. This synchronization process requires a temporary pause in external transaction processing to prevent errors or fund loss. Historical Context of Exchange Maintenance for Upgrades This is not an isolated incident in the cryptocurrency sector. Major exchanges globally routinely implement similar temporary suspensions. For instance, Coinbase and Binance have historically paused services for assets like Ethereum during its landmark “Merge” upgrade or for Bitcoin during Taproot activation. These precedents establish a clear industry standard. The primary goal is always user protection and network stability. By halting deposits and withdrawals, exchanges eliminate the risk of transactions being sent to an old, incompatible chain version, which could result in permanent loss of funds. Immediate Impact and Action Steps for Bithumb Users The announcement has direct implications for Bithumb customers holding or transacting FLOW. Users should note the following critical actions and timelines: Deposit Cut-off: All FLOW deposits must be fully confirmed on the blockchain before 11:00 a.m. UTC on January 29. Deposits initiated after this time may not be credited. Withdrawal Planning: Users needing to withdraw FLOW to external wallets must complete transactions well in advance of the deadline. Trading Continuity: All spot trading pairs for FLOW, such as FLOW/KRW and FLOW/BTC, will continue without interruption. Wallet Safety: Funds held in Bithumb wallets remain secure and unaffected; only the transfer functions are temporarily disabled. Bithumb has not specified an exact duration for the suspension. Typically, such maintenance windows last from a few hours to a full day, depending on the upgrade’s complexity. Users should monitor Bithumb’s official announcements page for the resumption notice. Broader Implications for the Flow Ecosystem and Market This upgrade signifies ongoing development within the Flow ecosystem. Created by Dapper Labs, Flow is a blockchain known for supporting popular NFT projects and consumer applications. Regular mainnet upgrades are a positive indicator of a living, evolving network. They demonstrate developer commitment and project longevity. From a market perspective, temporary exchange suspensions can sometimes cause minor liquidity shifts. However, because trading remains active, significant price volatility directly attributable to the maintenance is generally limited. The long-term effect is typically neutral or positive, reflecting improved network utility.

Observers and participants should view such operational pauses as a sign of healthy, forward-moving infrastructure maintenance. FAQs Q1: Can I still trade FLOW on Bithumb during the suspension?
