From the suggested mining pools, it adds up to be 91.613 MH/s, but the total Net Hashrate is 683.95 MH/s. I thought mining pools are supposed to contains the biggest hash rate, but for gold coins, the suggested mining pools all together only adds up to 91.613 MH/s.
gld.cryptcoins.net Pool Hashrate: 63.659 MH/s
gld.cryptcoins.net Pool Hashrate: 5.254 MH/s
gld.hashfaster.com Pool Hashrate: 21.70 MH/s
Net Hashrate: 683.95 MH/s
Where is the the rest 593.337 MH/s coming from? Is it all from solo miners?
