Bithumb, a leading South Korean cryptocurrency exchange, will temporarily suspend deposits and withdrawals for Neo (NEO) and Gas (GAS) starting 9:00 a.m. UTC on February 3. This move supports a significant upgrade to the Neo mainnet, ensuring a secure environment during the transition. Trading for NEO and GAS will remain active on Bithumb's spot markets. The suspension is a proactive measure to prevent transaction failures and protect user funds during the upgrade. Such actions are standard practice in the industry, reflecting responsible exchange management. Bithumb will notify users when services resume, typically within 24-48 hours post-upgrade.
