I think that such inventions are using the blockchain success, but they don't hold any value. They just confuse the consumers which think that they are receiving valuable cryptocurrency, but it holds nothing like that. The traditional companies found a loophole to benefit also from the blockchain technology, but it is just a fake as in other cases the consumer really hold a part of the mother company (like an investor), but in such cases it just holds some coupons just to spend more.
