I am mining on WoolyPooly since fall 2019 (Sero and Cortex) and I must say that I like this pool.
Even if it is relatively new and not yet that popular amongst miners, I gave it a chance and was not dissapointed until now.
There were no technical issues so far which would lead me to change over to another pool and never come back.
Mining revenue is not worse compared to other pools, everybody is welcome to put their rigs on and check it out themselves
The staff is very nice and supportive and listens to input from miners. So you are able to discuss your results, bring own ideas in and you will be listened to.
This is different compared to other pools, which does not even have a support channel on discord or telegram at all.
The pool's page is maybe not what you know from 2Miners, but it is written from the scratch and still evolving (which means that sometimes some hickups may occur, but hey, who is perfect today, funds are all the time safe, so don't worry).
In case you see any fields of improvement you are free to put comments / wishes here or on discord, so everybody has a chance to bring their ideas and in this way a very nice GUI, everybody is liking, could be build.
