Japanese crypto exchange bitbank said on the 19th that it would halt Bitcoin deposits and withdrawals from around 5 p.m. on Aug. 21 until around 7 p.m. on Aug. 24 for the planned eCash-related Bitcoin event, while other services remain available. GMO Coin said on Aug. 7 that it may suspend Bitcoin spot trading, BTC/JPY crypto FX and leveraged trading, and BTC deposits and withdrawals when eCash reaches block 963,648 around midnight Japan time on Aug. 23, but has not set start or end times or confirmed a pause. eCash's live roadmap now calls the event an Alpha stage issuing practice ECX, followed by Beta around Sept. 20 and Mainnet around Oct. 31. Earlier materials described block 963,648 as a fork point with a 1:1 ECX credit. Both exchanges warn of replay, volatility, liquidity and early-chain risks, while eCash says existing BTC will not be altered.
