Not being successful while representing the project truthfully is not evidence of scam. Not being successful while dishonestly promoting the project as something it absolutely is not, is.
False equivalence. This is not a new product. It is a lazy copy of other people's code with a few settings changed. Those changes do not equate to a 'new product' any more than Heinz baked beans being sold in a store-brand tin equates to a 'revolutionary' new product.
You want to believe that all this coin needs is marketing in order to be successful? That is, at best, magical thinking and, in actuality, more a plea for the 'devs' to try and find a bunch of greater fools to pay more for your coins than you did, than a viable model with which to assert value. There is no reason for anybody to want to buy SIGT but plenty of reasons for them to steer well clear of it.
