I'm not a crypto vet, haven't been around these parts nearly as long as most of all of the people posting on this thread. So, I can't necessarily offer the perspective of along history with Denarius or crypto in general.
What I can say is that, being a newb, I've bitten on the hook of several scams unfortunately. And Denarius is like none of those. I discovered it a couple of months ago, and was struck by the level of engagement and openness that Carsen has in the discord, the level of continued development, and smart, passionate supporters that are contributing to the project and community. That is a lot different than the several faceless, anonymous, money pandering scamcoins I've seen, with devs disappearing once pre-mine or ICO or donation funds have reached their fancy, or dumping their huge hordes of coins on exchanges and pocketing the BTC while leaving the price at virtually zero for the true investors.
Granted, I'm not the tech savvy dude that's gonna read the github and compare the code to other projects. Just can say that this is definitely not an abandoned project, and it is garnering new interest. It's passed the smell test for me as being legit. And so, I'd have to imagine it's definitely worth looking more deeply in before calling it a scam, cause it's not like any scams I've seen.
