We going to make Hubcoin hard fork on next week (or a bit later).
For fixing 2 bugs + possible adding safe math for additional security.
(My own premine freezing code works perfect, both bugs inherited from token examples at Ethereum.org. )
It is only one possible way to enable deposits/withdraws on CoinExchange.io and we agreed with CoinExchange.io admin about it.
Balance distribution and Hubcoin ownage will be 100% same, so there will be no problems.
It will require only to change token id on wallets.
Then we continue Hubcoin development, will follow promised goals but will not limit us to it.
