Project seems rather interesting,website seems rather legit, lot of informations, lot of work there.
Does not look like usual scams but I have got some questions to be sure it's not a ponzi like
1) mining facility is not built right now, so, how is this possible to compute orders already?
2) Who is the team? names ? Where is the company located? proof of existence?
Here is dev response
"We have a prototype that is running, that's how people can test it. Since this was a free airdrop we don't instantly have a ton of money to be thrown at legal so the team will stay anonymous in order to protect ourselves. Company is located in the USA in Wenatchee, for the very inexpensive power rate of 2.3 cents per kilowatt hour."
