Yes! We run team solo mining "block parties" at upendo.xyz you can point your hashrate there or you can also buy extra hashrate on our site to add to the party to increase the odds of finding a block. We source hashrate from rigly.io which is a hashrate marketplace.
I can vouch for Upendo -
https://upendo.xyz - (I'm also the co-founder)
I was inspired by Willi's block parties here and wanted to make a place where folks can solo mine together easily.
You can buy hashrate through our platform or join w/ your own miner.
Bitaxes welcome.
We mine together via CK Pool and we're running our block party every other Saturday.
