It seems that every month or so there is a gambling site that is released that is run under a smart contract with an alt-coin. These alt coins are usually large or medium cap like ETH, TRON, EOS, NANO, etc. So I am not surprised to see another one launched to give an alt-coin some actual real world use, I think its great for adoption.
However here is the issue. Most crypto gamblers usually only hold BTC, LTC and ETH. They very rarely will go and purchase an alt such as NANO to gamble with. Sure it has lots of trading volume however most of the NANO use right now is just for speculation. There aren't too many gamblers who are hodling NANO right now. Usually what happens the site will get very little usage even though its an interesting concept.
