Smartcontract was making the total token/coin in the markets have no control as anyone can issue their own asset and ask garbage exchange site to list it. It's not all of the coins are focused to develop the utility/real use case of tokens. The problem is scammers were also contributing a lot to the total tokens in the market as they will be issuing new tokens and then ignoring them after they scammed some money from investors. Blockchain has various use cases as long as it is well developed by trusted developers. The problem is there are lots of scammers are creating scam projects. You can be sure that those top coins have real utility usage but doubt about the rest. I can't say the range for how many tokens that owned utility use case but hundreds of coins in the market have it and the rest didn't. it's hard to count how many coins that exist in the market now have a real use case.
