Ethereum demand is always their, the main reason was transaction fee. Huge growth of ethereum only due to that fact.
ethereum reducing its total supply by burning is really effective to increase the price in the market, it make the market not having too much supply and cause the price to increase easily but its true that most of projects are still created in bsc day by day. maybe if ethereum can make the project get back to them again it will increase the price even more but price increase will also make using eth more costly.
