Those are pretty obvious scams, but I think even popular tokens like EOS and TRON are some sort of scam too, on paper they kinda make sense, but I don't see them successfully competing with Bitcoin or even Ethereum, and most likely they will just die in a few years.
Exactly! Even Tron's whitepaper was a copy paste here and there. Many of these coins represent a hope that it will become "the one" or will be very useful in the future. In reality, they are most likely would be a soft scam, just like a herbal medicine that offer many false claims. However, maybe they will deliver the product and fulfill their promises, we just don't know yet.
Still, the investors and the market are just irrational considering the price compared to the present value.
