I haven't been specifically tracking botnet domains, Theo,
One possible reason for the decline in the size of DGA networks might be 
due to the algorithms being cracked and registries being more willing to 
cooperate. Bad actors may also seek to obscure their footprint as much 
as possible and using multiple algorithms with smaller networks is an 
effective way to do it. With discounted new gTLDs, they also can 
distribute DGA domain names.

Again, the scale of one year registrations works in their favour. Even 
.COM has about 43% non-renewals (it varies by month/season) for first 
year registrations.
