As someone who is interested in this space, you have a proper way of looking at it. Most tokens are just scams outright, or if not scams, have communities which are totally unwilling to solve the technological problems inherent of their coins (see Bitcoin's high fees, limited block size, lack of privacy). One example of a decent currency which runs counter to this trend is privacy-focused Monero, though the developers/community don't bother to market it in the same manner as many other coins, to a point that on of the main criticisms of it is its comparable lack of volatility, amusingly enough.
tl;dr There are quite a few innovations that have been made by various actors in the cryptographic currency space, most of which are entirely drowned out by a torrent of mind-numbing get-rich-quick scams and stubborn, close-minded speculators.
