If its not pump and dump coin as they said then we investors who hold the XAURUM token its worthless to us , and the gold which was never under our control means we don't own any gold. 
it looks like the devs are collecting our money to buy a gold which we will never seen in the future but if you pump and dump at least we can make some profit more that holding the imaginary gold.
So basically Xau is not for investors rather its for those who want to buy gold and let Xaurum team control it for them.
Actually I'm going to dump all the worthless Xaurum tokens I have soon ,and I will use the money to buy some gold and silver.
