Hi,
I have configured my Bitaxe Ultra 204 with bc1qeuupt2tgerfum8jclt8aklu9cdmzzkwml9lg7c.Reen1026 (I wasn't sure if I can have a dot and username after the address but it seems fine on the BitAxe) and it has started mining now.
My Bitcoin receiving address is bc1qe2unejwrtffrnzg8wqlkqfag8qdqw242v9xjq8 . SOLO MINERS UNITED!!!! THX for this opportunity!!!
(Miner's name - Reen1026 ) Cheers!!!
