GMO Coin may suspend several Bitcoin-related services when eCash takes its first balance snapshot at block 963,648, expected around midnight Japan time on Aug. 23. The exchange said on Aug. 7 that any suspension remains conditional, with start and end times undecided. Potentially affected services include Bitcoin spot trading through GMO's dealer and exchange platforms, BTC/JPY crypto FX and leveraged trading, and BTC deposits and withdrawals. The live eCash roadmap now describes the event as an Alpha stage that will issue practice ECX, followed by Beta at block 967,680 around Sept. 20 and Mainnet at block 973,728 around Oct. 31. Permanent ECX would be credited at the Mainnet snapshot, while practice units could be burned to redeem the permanent asset. An integration guide updated Aug. 11 still describes block 963,648 as a fork point with a 1:1 ECX credit and says final parameters, including the fork height and replay scheme, will be published separately. GMO has warned that shared Bitcoin address formats and opt-in replay protection could create transfer risks, while volatility, thin liquidity and early chain instability could widen spreads, trigger margin calls or forced sales, or cause transaction reversals. ECX is separate from XEC and from BIP-110, another Bitcoin soft-fork proposal. GMO and eCash say the new chain does not alter users' existing BTC. The block remains a planning point rather than a confirmed freeze, pending any further GMO notice.
