Well, decentralization has its cost for sure, but not for the aggressive Eth fees!
Investors want decentralized solutions, but don't like spending high fees just to make simple transactions.
That's why Avax is gaining popularity for its balanced decentralization and transaction cost.
Other than Avax, I see Tron TRC20 blockchain is cheaper, faster, and more decentralized than other solutions in the market. But, adoption is key for the life of any project. With new Defi projects entering the market, like the Ferox/frx one, using TRC20 is healthy for the Tron ecosystem and the project itself.
So, there is still great potential in Avax, TRC20, and other more decentralized technologies.
