This will be a challenging project. We all are used to see regular gambling sites but this one seems totally different. Anything new most of the time takes longer time to establish.
I would say the opposite, it is not totally different but it is completely the same as other hundreds sites out there because the script/software can be bought easily through codecanyon. The main script itself is worth no more than $200, and the add on game for lottery costs him $30. For all games, someone need to spend around $800 only to own a gambling site like cryptolottery bet.
