If you believe the devs this is worth mining now. But just remember the only way it will succeed long term is if it IS NOT profitable to mine. So you could take a chance and mine, hope you get payed out before the devs run out of money (or hope that the hash increases enough to fund the devs to pay you. They probably have money to pay for a while. So it will APPEAR legit soon. But in time it WILL crumble..
I will admit that I got caught up in a scam like this. GPU coin had an officially licensed business in the US. They had a website and sounded very official/serious. They offered IPO and sent out GPU's to people (at first) who bought them or won in giveaways.
But then it turns out that they only sent a couple, and that they were just instantly reselling the coins sent to them in purchases in order to profit. One day they just disappeared and hundreds of people were left wondering when their GPU was gonna ship... It wasn't until after a couple weeks when people weren't receiving shipping notifications, and then the coin crashed and Game Over man.
Edit: I will give them the courtesy of stating that this COULD, "COULD",
possibly not be a scam. But even if it's not a scam, it'll fail because they're doing it wrong.
