Syscoin [SYS] will be upgrading their blockchain from Syscoin 3.0 to Syscoin 4.0, a new blockchain with a high-throughput transactional layer and a zero counterparty "bridge".
All Syscoin 3.0 users will retain the balance of their Syscoin 3.0 addresses, which will be migrated to the new Syscoin 4.0 blockchain.
Users' Syscoin Bittrex exchange balance totals will reflect the same total that they had prior to the swap in a 1:1 manner. Once the swap is complete, Syscoin 3.0 tokens will no longer be supported or be traded on Bittrex.
Bittrex will re-enable the SYS wallet when we and the Syscoin team agree that the migration is satisfactory.
Note: Bittrex will be closing our SYS wallet and may stop trading the token to take accurate snapshots of balances. If any SYS deposits you had sent to Bittrex are not settled (e.g. marked as pending) by 10:30 AM PT, on 6/4/2019 (5:30 PM on 6/4/2019 UTC), you may not be credited with SYS.
We would like to thank the Syscoin team for working closely with us.
