High fees are due to the growing volume of transactions and the trend of Defi seems to depend entirely on Uniswap. Actually this is one of the most prestigious exchanges and it is a good place for quality defi projects to survive.
I've also heard of Stakenet being a very good DEX but it doesn't diversify a lot of coins. That is why it is not good enough to gain the support of many traders. I think you should create a bounty campaign instead of just advertising with theoretical images like that.
