I don't think his plan was to scam when he started, but if he was trying to pay back one loan by taking another, my guess is he has more debts elsewhere too. That could put his total debt far above an (average) annual salary where he lives, and my guess is his debt on Bitcointalk is a lot easier to walk away from than debts he took in real life.
I think you are right, I bet that he is heavily in debt to some of the manufacturers he make contact with. As far as I remember, he is communicating to 6 manufacturers in building his products. And there is a greater chance he has more debt in real world other than this.
This is his estimation for product pricing.
Aside from his loan to DireWolf, he said that he needed more amount of BTC to fund his ongoing business
I just can't take this because I also lent him my personal money
that is my allowance and it's a lot for me as a student.
