Yes, in my opinion this sounds as an concern because when supply exceeds than the demand then also it's called the unproductive business and this is not good at all because most of the smart contracts are hold by the Ethereum Blockchain so this is an concern on which the team have to think upon.

And second concern in my opinion is, as per Blockactivity Ethereum stands on second number below the Steem but yet Etherium almost used it's Block Space and Transactions are slow, and i hope that the team will come up with the solutions soon.

Thanks for sharing this post with us and wishing you an great day. Stay blessed. 🙂
