Bithumb to suspend GRAM transfers today for network upgrade

The South Korean exchange said deposits and withdrawals for GRAM will pause at 10:00 a.m. UTC as it supports the Gram network upgrade.

Fact Check
The official Bithumb notice (feed.bithumb.com/notice/1654177) confirms GRAM deposit/withdrawal suspension beginning 2026-07-22 19:00 KST, which is exactly 10:00 AM UTC as stated in the claim, for the TON (Gram) network upgrade. TokenPost independently corroborates the 7 PM KST start time, and the Coinness lead matches. Note the GRAM token is the rebranded Toncoin (TON), consistent with the 'Gram network upgrade' reference to TON Global Version 15.
