The Japan Cryptocurrency Business Association has officially announced its plan on how to deal with the possibility of a Bitcoin protocol split on August 1.

                         Withdrawals

The Japan Cryptocurrency Business Association (JCBA), formerly known as the Virtual Currency Business Study Group, announced on Tuesday its official plan for August 1.

Thirteen bitcoin exchange members of the association have agreed on how to deal with the possibility of a Bitcoin protocol split, which is expected on August 1 at 9:00 am Japan time, the JCBA detailed. “The occurrence of forking affects the transmission and receipt of bitcoins by all bitcoin users, and it is expected that all related virtual currency exchange operators and service providers will be seriously affected.”

The exchanges have collectively declared:
"We decided to temporarily stop accepting bitcoin deposits and withdrawals at each exchange…We will stop only the services related to depositing and withdrawing bitcoins, but we will provide our regular services for other virtual currencies and legal currencies."

Currently, the following 13 bitcoin exchanges are members of the JCBA that have agreed to this plan.

"We plan to update the acceptance of bitcoins and the resumption of withdrawals by 16:00 August 4, 2017 (Japan time)."
