ETC Hard Fork Plans
To protect against the ongoing attacks first targeting Ethereum and now Ethereum Classic, the Ethereum Classic Project announced a hard fork scheduled for ETC block 2,500,000, approximately 05:20 AM UTC Tuesday, October 25th.
Bitfinex users holding ETC do not need to take any special actions; balances will automatically be migrated to the new chain.
We will temporarily disable ETC deposits and withdrawals about 20 minutes before the hard fork will take place. Trading will continue as usual during this period. As soon as the hard fork has been completed and the Ethereum Classic network has returned to normal operations, deposits and withdrawals will start being processed again.
ETC owners who wish to maintain full control themselves over which chain to keep their ETC balances on should withdraw their ETC to a local wallet before withdrawals will be deactivated. We will not be processing withdrawals on the deprecated chain and are not responsible for returning any ETC from the deprecated chain back to users.
More details on the hard fork are available in the announcement published on the Ethereuem Classic blog.
