That's so true. Most altcoins have turned out worthless as they had no real products in this space. all that they do is just to create hype about their project and lure inexperienced crypto investors into them. Ethereum blockchain network network invented a very good use case of smart contract but this has been abused terribly by greedy project managers
That is because of the freedom they gave to create a coin easily, smart contract has become the root of all scam project. If ever that they can add features on creating a coin with additional security not to the developers but to the possible users, this may be able to increase alertness and to avoid making a new project with an intention to scam the community.
