cpu coin are also bad, and worse than asic, because a random dude could use aws instances to own a large amount of hash in no time and centralized the mining activity
Well, is a GPU coin also bad then? A random dude can use AWS GPU instances to own a large amount of hash in no time.
https://aws.amazon.com/ec2/Elastic-GPUs/no they are not as efficient as cpu aws instances, they are far worse, inf act you don't see it often used, instead aws instaces are perfect for cpu coin, but they will centralized the hashrate too much and kill the coin
