12. Why is my public address balance zero on the distributed ledger after my purchase?

Our platform has the designated accounting system to compute the correct digital asset balances for our users. You can imagine the internal operations of banks. When you make a deposit at your bank, your bank account balance reflects the amount that you deposited; however, the actual money you deposited may be immediately removed from your account for banking activities such as money lending, interest accumulation. Of course, our internal activities are not the same as the banks, but you can be assured that this is a normal phenomenon.

13. Can I see my buy and sell transactions on the public blockchain?

The public ledger cannot accurately reflect your actual buy and sell activities as mentioned previously our system shares some similarities with banks. Nevertheless, this does not apply to the case of sending and receiving digital assets between wallets. The transactions between wallets will be reflected on the public ledger. Therefore, the conclusion is the public ledger reflects the wallet-to-wallet transactions, but not the conversion from fiat currencies to digital assets, and vice versa.

14. About the transaction amount on invoices

The 1% amount of your buy/sell orders appears on your invoices represent our service fee from each orders we receive from you.
