Hello, generally speaking, the biggest advantage of this is convenience, no need to insert the optimal shield, no need to enter the password. Mobile phones are also available, so buy them quickly. It won't make you make a mistake when you are busy near 3 o'clock, and the transaction is unsuccessful.

But the security is less, but please rest assured that you won't be short of money, because this is the binding of your bank card and Huaxia Fund, and the funds can only be exchanged between these two accounts, and it is impossible to turn to a third party. It's just that if someone wants to hurt you, you can use the money you urgently need to buy Huaxia Fund through trading. You have to wait a few days to redeem it. This is the only problem, so you need to set a difficult password. In addition, I would like to remind you that there is no SMS reminder for subscription, only subscription confirmation and redemption.

If you don't understand, sincerely welcome questions; If I am lucky enough to help you, please adopt in time! thank you
