Why so much drama for altcoin signatures?
I doubt about the payment , OP said everyone will recieve 1280 XAU , while XAU price is 0.6 BTC , it is impossible , I think it must be 0.1280 XAU , am I right ?
No, it is split into 8000 xaurums ,so that 0.6btc = 8000 xau & you will get around 1.7k coins @ current rate.
