Hello SUMO community:
The community is well aware of the centralization issues of mining SUMO. We strife for a decentralized network and try to spread the hashrates more widely over smaller pools.
At one point today, the 2 biggest pools (Hashvault and (Un)fairpool (yes I like to call them that because of their rediculous fees)) controlled around 90% of the total hashrate which is OBVIOUSLY very bad...
We've recently relaunched our low fee (0.1%) PPLNS pool for SUMO:
https://sumo.spacepools.org/Payout threshold is set to 0.5 SUMO (there will be an option to modify this threshold later on)
We also have a very active discord and a special #needhelp channel for all your questions about mining:
https://discord.gg/QBmtnsWSo what are you waiting for! Let's make the network decentralized again and start mining on our pool!
Also I would like to encourage people to use a new mining pool list:
https://sumokoin-pools.morin.io/Help the guy out and contribute to the project on github or, if you want your pool listed, you can submit an issue (see the button below the list of pools).
Unfortunately sumopools.com isn't getting updated anymore, we tried to contact the owner a few weeks back and have yet to receive a reply of him.
