Re: exchanges
If you see the coin listing elsewhere - on miningpoolstats, for example - you have to be aware that they might list the exchanges wrong.
My mistake was that I haven't double-checked names and everything, and was too lazy to create a wallet locally. This led to a night of mining and throwing the results away to an incompatible address.
TLDR: pay attention, this is XAU (SatoriGold), not XAU (Goldneum). It is NOT listed on Nanu as of yet. Do NOT try mine to a goldneum 0xsomething wallet.
Let my mistake be a lesson for others =)
