00 1 Do I have to buy it by credit card?

00 1 must be purchased by credit card.

If the user uses a debit card, it cannot be started. It is clearly written in the SMS notification that the user carries his ID card and the credit card when registering for purchase.

Finally, I suggest that if users don't want to buy after winning the prize, they'd better register, otherwise they will be blacklisted and will never win the prize again.
