to me the scam is that tether is worth one dollar! to create this peg--- will require the creation and dilution of tether constantly- but if your asset gathering aka taking bitcoin and giving out hot air tether-- you now have assets which are not pegged to one dollar and float. under a normal business model this would hurt but if you got the asset for nothing it doesn't matter. if it was a real peg .. it would grow as needed not in 100 million blocks
