XAUt0 is Tether’s tokenized gold product — essentially a digital asset representing physical gold, backed by gold reserves.

is this Gold reserve proven somehow?

Yes. You can check out the Tether's web page and search for more information on that (https://gold.tether.to/).

nice! That sounds quite good

Yeah, and since it's not just any crypto company, but Tether(USDT), one of the biggest entities in whole crypto, it's pretty trustworthy, IMO.

Btw, the bars are in Switzerland. For some reason I imagined they were in Fort Knox! 😅
