There is a new gold-backed or metal-backed crypto coin OROCRYPT:
https://orocrypt.com/ they even got Chinese language option.
Xaurum has competition and there will be more, which will only expose how incopetent this team really is. I think on the long run Xaurum will not succeed.
"Orocrypt is a Panamanian-based company ..." No, thanks.
Look at their team. Looks like a bunch of retirees decided to have some fun in crypto world

I think they have three or four competitors with similar algos and many more coming in because competitors are now seeing the success of Xaurum imagine,only Xaurum perform better when crypto currencies are turning red and it happen in so many occasions.
Anybody who wants to copy Xaurum has many problems. Besides all the mathematical, storage and legislation issues, the biggest issue for copycats is this: They will not earn any money.
Xaurum is a gift to community, not to Xaurum creators.
Xaurum team works on extremely low income. This basically covers the costs of gold storage and some development.
Our only goal is totally in sinc with the rest of the holders - make Xaurum more valuable every day.
Every copy seen till today has at most 5% of Xaurum features. They do not come even close to being real competitors of Xaurum.
Xaurum project, devs, just need a time, and time is on Xaurum side...
