i had the same question to the support:

As of Monday, 8/4/2014, CryptoRush 2.0 decided to open up beta testing to the general public. Simply go to https://cryptorush.in and click 'Register' to create a new account with the same email address associated with your CR 1.0 account. Once the beta phase is complete, your previous balances will be merged into your new account.

As of the latest updates, you can view your previous balances by going to the Portfolio page and clicking the 'Show 1.0 balances' button. Additionally, we have also begun the repayment of come of the coins from the CryptoRush 1.0 balances. So far we have converted BTC balances to CRB-B and LTC balances to CRB-L. These are CryptoRushBonds-Bitcoin and CryptoRushBonds-Litecoin and will be used as an accounting measure to keep track of what we have repaid and what is left to be paid on each account. There are also markets for these Bonds if you wish to trade them.

Please provide us with any feedback you may have (site suggestions, bugs to report, etc.) by submitting a ticket or emailing us at support@cryptorush.in.
