Yah! What could be a scam? Now there are only real projects on the market. No one self-respecting investor will invest in story without a prototype, at least, and even without a working product!
Real projects or not are not a conclusion to as whether the token or coin associated will be a success. I have seen a lot of non-real projects become big successes. Look at EOS for the biggest example. No prototype no product just copypaste code. And when they did get the product moving, it just became worse. Investors is normal to want to invest in ideas but we now learn that ideas in crypto are literally 100 ideas a day, and all implementable at code level.
Utility is still the major obstacle! Product can be great but if nobody uses? Product can be stupid kitties but if people use it, it becomes a success!
