Woofun AI reports that Bithumb will suspend Casper (CSPR) deposits and withdrawals starting at 10:00 a.m. UTC on June 30 to facilitate a scheduled network upgrade. The exchange has not defined a specific resumption time, noting that services will restart only after the blockchain stabilizes following the update.

The Casper blockchain, a proof-of-stake platform targeting enterprise adoption, is undergoing this maintenance to enhance scalability, security, and developer experience. While the upgrade is a routine part of the development roadmap, it necessitates a temporary freeze on fund movements to avoid transaction errors or potential loss of assets during the transition.

Notably, trading pairs for CSPR on Bithumb remain fully operational throughout the suspension window. This distinction allows traders to continue buying and selling the token even though they cannot move funds into or out of their exchange accounts during the upgrade period.

Per Woofun AI, the exchange has urged users to finalize any pending deposits or withdrawals before the June 30 cutoff to avoid delays. Historically, such maintenance windows last from a few hours to a single day, depending on the technical complexity of the specific network changes being implemented.

This suspension represents a standard precautionary measure designed to protect user assets while ensuring a smooth migration to the updated infrastructure. For active traders relying on arbitrage strategies or cross-exchange transfers, the inability to move tokens temporarily introduces friction that requires careful timing of capital deployment.

Market participants should monitor official Bithumb announcements for precise updates on service restoration. This incident underscores the operational reality that even mature proof-of-stake networks require periodic halts to maintain long-term performance and security standards.
