UNO is valued first for what truly is. It's a vetted, rare, fair launch, low inflation cryptocurrency, pure POW and no POS, with a merchant network, devs and a solid long term community. And yet it is the best store of value in Crypto. Nothing backs it except it's community. Beyond that, it's an open platform that anyone can build on.
But if you're also asking, what is giving Uno it's current value? We value it simply because it is Uno. It is what it is. Very few cryptos are valued in this manner, almost as a rare commodity. It's really the first sustained rare crypto currency that is valued for its rarity. It is authentically Unobtanium.
Here is what it is not: there are no fake or prentend projects that give Uno it's value. There's nothing there to disappoint or fail. It's not a company, or an app. There are no telephone calls, no messaging apps, no deals with Africans, no built in exchange. It's not backed by fake bullion or hash contracts. It's not backed by anything other than its community, and its story.
Uno has survived a huge pump, loss of devs, a soft fork, 5% of it's coins being stolen and dumped at Coinex, loss of 1000 coins at MintPal.... there have been hardships and every single time Uno comes through stronger. It's a survivor.
It does definitely stand out from the rest. What merchant network ? I can see this being used in nightclubs in the future ...maybe in a VIP area or in Vegas. Something feels premium about it..
