Solved. Coins already been credited.
Thanks for the support.
Best of luck.
Can I send my Grin coins to Hotbit from this pool? If yes, then how?
Yes there is an example on the payments page:
But my 12 Grin has successfully reached Hotbit. 
How can I configure different rigs with different rignames? How can I assign different names of workers in Bminer, for example?
For this pool you will need to make new accounts for each worker if you want to view stats of individual rigs at pool level. It does not yet support multiple workers per account (it will record the shares submitted, but will sometimes attribute shares to other rigs submitting to the same account). There is no share-loss from submitting work from multiple rigs to same account but if you want to track hashrate of individual rigs you will need to make separate accounts for each rig/worker. For mining software just set the username to your mwgrinpool account name.
My average GPS is consistently reported about 30-40% lower on the pool than is reported by grin-miner. Is that to be expected?
I’m afraid this is the situation on all existing pools. Some of them just shows more or less acceptable graphrate. I prefer MWGrinPool for this reason.
If you’re mining C31 with a 1080Ti or 2080Ti, then the lower reported GPS is due to the pool assuming fidelity 1, whereas grin-miner currently only has fidelity ~ 0.7 A fix is in the works…
Ah thanks for the info. So when the fix is released, we’re likely to see a decrease in GPS reported by grin-miner?
John, mw. somebody were able to run 8G nvidia cards on C31. how is this possible?
I already mentioned that possibility in https://forum.grin.mw/t/gpu-mean-memory-reductions
Also, of the 2x31 = 62 bits representing the two endpoints of an edge, you don’t need to store the 12 bits that determine one of the 64x64 buckets that it ends up in.
All my rigs are online and hashing…
Hey ! Been mining 48h straight, and no immature balance show up. I’ve switced to the 13.2 BMiner version, and since then, nothing…

Important Announcement
Well guys, it’s been a hell of a ride with plenty of ups and downs, but our team at MWGrinPool does not feel that it can offer the level of reliability that our miners need to stay competitive. While we are proud of the technical milestones that we have achieved, we believe that with our current reliability issues and low market share that a return to break-even level for our pool is unlikely. We appreciate all of you trying us out and sticking with us as long as you have, and will look fondly on this adventure.
Our stratum server will stay up until Monday February 4th and payments will continue until March 4th. Thank you and good luck!

Please note that our pool will be continuing operations with weekly upgrades being implemented at approximately 10 AM PST (6 PM UTC) on Fridays . We recommend that you have a back-up pool configured during these updates, since there is a possibility of downtime. Thank you.
Pool is alive and well.
Yep, they just changed their mind.
Is mwgrinpool down? cant access the website but my rigs are connected and submitting shares…i dont want to change pools as the rejects are high elsewhere.
MWGrinPool administrator here.
Please be aware that we are planning on migrating our pool’s username system today (April 21st) to convert all periods (.) in current usernames to underscores (_). This change is being implemented to facilitate the addition of support for multiple rigs mapped to one user account. There will be a 1-month grace period where your regular username will exist, but you will need to eventually start using the username with underscores so that periods can be used to parse rigs and workers connected to a specific user account.
If your username has no periods in it then should not be affected by the username syntax change. If you see anything out of the ordinary then please let us know. Thank you.
