Just because some crypto coin utilizes the blockchain doesn't make it secure or popular---a lot of coins have been attacked because of how insecure their networks are. It's a massive single point of failure.
If it's not popular then people won't use it for their business, either their business is a scam or legit, this is also supporting your own words, that :
Blockchain is a buzzword to help businesses and scammers attract capital. I have never liked the idea behind a whole blockchain industry. It's 95% hype and 5% utility. One day that hype will lose its momentum....
Scammers won't be able to attract people if blockchain doesn't look enough secure, popular or whatever it is
Bitcoin is known for its immensely powerful network---security that helps maintain its data integrity. I haven't seen many people praise Bitcoin because of it being a blockchain. People value Bitcoin's network.
You are right, in this matter. Still, none of us can'r deny the fact that Bitcoin is using blockchain, Bitcoin has its on blockchain.
