Buy a CDN acceleration service and just drain the traffic, attackers need costs too, it's ultimately a war of attrition.

How much does it cost to launch a DDOS attack service?

Kaspersky has published an interesting analysis of the cost of DDoS attacks.

Experts estimate that the cost of a DDoS attack using 1,000 cloud-based botnets is about $7 per hour. And with DDoS attack services typically costing $25 per hour, that means attackers can expect to make a profit of about $25 minus $7, or about $18 per hour.

But the overall cost of an organization's defense against a DDoS attack can often run into the tens of thousands or even millions of dollars. So don't think about launching ddos attacks to get improper gains, now the state gradually introduced various policies and improve laws and regulations to protect network security, damage to citizens' network security behavior is bound to be the country's heavy-handed crackdown.
