I closed the first poll as a three way poll isn't that accurate, especially when the first two options were similar enough.
The 100 billion option could be polled on but is anyone actually enthusiastic about it? As well wasn't the point behind this other people's superstition? The number 8 is an important number in East Asia. I'm not sure if the number 10 is considered good anywhere.
I think two options are good enough, but what if someone doesn't want a change?
Well the first option is effectively the same as no change, isn't it?
Whether you like or it not - anybody can change the total supply by sending as little as 1 NEM back to the genesis account. This isn't something unique to NEM but something you can do to any coin, it's called burning.
