btc.com? let me go in and look at my account. I dont recall mining there at all in 2020.
yep it is pool.btc.com - the last payment I show from them in my records is 09/20/2018 - but it came from that same address as the one above.
did they at some time have merged mining that they finally paid out or something?
here is my payment screen nothing since 2018 and it was even a different address than the one I used for btc.com
but at least I can mark it as from them even if I don't know why they paid me.
edit:
in looking back they did have merged mining for NMC, ELA and VCASH which I had no addresses added for those. So maybe they did a clean up and converted them to btc and paid it out - not sure.
Either way, I can consider this closed. Thanks Phil
