Is anyone else concerned at all with the huge portion of the mining being undertaken by suprnova right now? They are contributing well over 51% of the current hashrate...

https://miningpoollists.com/hush/

We have been aware of this for a while. The community has been increasingly adding more mining pools with non-suprnova pools seemingly becoming more popular. In Slack we whole-heartedly advocate not to mine on a pool that has majority hashrate.

I'm mining on suprnova. Can you guys give me a reason not to?

Because it is in nobody's best interest to put over 50% of hashpower in a single pool. Move to hushpool.cloud for example which is also big enough to even out your income.

I don't want to sound like an asshole, but that reply doesn't convince me to move. I find suprnova easy to use and convenient with plenty of info. I need a real reason why I should move.

I understand your reasoning, don't get me wrong. But in the spirit of decentralizing currencies it is never a good thing if a pool has over 50% of the hashrate. If you are interested in the coin and interested in longer term holding instead of selling as you mine, you might want to learn more about it, as it can impose a real threat on a coin;

Such abuse would not even be very obvious, other pools could see their luck go down or get more orphaned blocks.
Some bitcoin pools in the past have volunteered to give up part of their hashrate in favor of preventing going over 40%, that should give a hint.

Attacks are possible even with one third the hashrate: https://arxiv.org/pdf/1311.0243.pdf
