Personally, I can tell you responsibly, but all lottery methods are for fairness, because I can tell you responsibly, such as issuing electronic coupons. If you rob me, you will never rob me, because I will use software to rob the coupons, so how can you rob them manually? So, if you don't take this lottery, then those who help others grab electronic coupons will grab them directly for you, and you can't even see the shadow of electronic coupons. Therefore, you must draw lots to ensure fairness. Otherwise, the so-called $6,543.8 billion electronic vouchers will basically be distributed to those who specialize in bonus hunter.
How can I put it? In fact, this is really for the sake of fairness, because at the beginning, e-vouchers were issued directly, and then there was a very interesting phenomenon, that is, most of the e-vouchers with high discounts were robbed at once, and ordinary people could not grab them at all, so some people later reflected this situation, and every time they issued e-vouchers, they began to be changed to lottery, which was nothing serious. Basically, as long as you participate, you may win the lottery. Of course, the premise is that you have never won the lottery. Generally, if there is a lottery ticket, it is basically impossible to win the lottery. Because it is also a waste to send you, the way to win the lottery is fair.
Generally speaking, the reason why lottery winning is adopted is because lottery winning is relatively fair. If you don't take this method, it's almost impossible for you to grab a better coupon.
