Since NUD is a CPU coin and is very likely to remain so in the foreseeable future your rewards would be large and the potential to earn for your effort maximized.
Wait what? No... no, thats not how it works.
In fact, because it is a CPU coin your rewards will be small because you will be competing with cloud-miners and botnets.
Unlike a CPU coin, a GPU coin is more egalitarian because a cloud-miner can't just spin up 200 instances and have a 200x advantage. or to be more precise he can, but those cloud instances will have crappy GPUs and he will not get a good return on that investment.
CPU coins will typically have the worst chance to earn profits.
It is not the cpu coin. It was planned to be but it turned to be regular scrypt. But not that is what rasing my interest here but the tor anon
