Well that is not entirely true. The use case is to be a rare collectors coin as outlined in the Whitepaper. It doesn't need to be anything more than that.
URX has one of the lowest total max supply counts in the entire industry at 235,000.
And for any scientist out there, Uranium-235 is a great natural resource isotope. I think the coin design is very unique.
"Collecting" crypto coins is a joke ... it's a test how dumb a man can be to belive in such thing...
URX max supply is nothing more than a number written in the code. It's not natural rarity like gold or uranium. Someone who put there 235000 was able to put there max supply will be 10 coins or 2 coins .. Does it make it more valuable ? I don't think so ...
You said that this coin design is very uniqe ... I would rather say - no it's not uniqe at all. It's just another clone of bitcoin code with changed PoW algo and small max supply (probably to pump the price fast , but that plan failed).
I mined this coin too for some time but i gave up ... It's time to understand that such kind of coins are now part of the past. There is no place for bitcoin clones anymore...
