The time at which scalpers buy tickets becomes irrelevant. They can resell tickets at arbitrary-high-price + margin because buyer know they will receive refund for the exceed amount, thus pay only (final price + scalper margin) for the ticket eventually.

Bonus: buy ticket from scalpers after price settled, you will get a determined price, no more guessing and find inner peace.

The problem for scalpers is that if they buy too many tickets, the final price may become too high to be attractive for real buyers.
