8
According to Qi Zhou (our CEO)'s testnet demonstration (you can find this video on youtube), which statement related to "secondary" in a user's balance is correct?
It is the sum of all balances other than the primary account
According to Qi Zhou (our CEO)'s test-net demonstration (you can find this video on youtube), if one clicks the "Transfer Balance" button, what will happen?
Secondary balance will transfer to primary one.
