I found a video of Mark Cuban explaining this:
https://youtu.be/QEoBeIdwuRgDo you think Ethereum has potential to become store of value? Why or why not?
I think so, because the gas fee of Ethereum which is too high. So, Ethereum is a store of value or just an investment and not a currency. People now always find other coins with small transaction fee in order to withdraw and lessen the gas fee if they use ETH. Even me I rather use XRP for withdrawal transaction or AVA coin to prevent a large amount of transaction fee.
In fact, BTC and ETH are becoming gold and silver in the cryptocurrency market, with high transaction fees and price fluctuations leading people to use ETH as an investment rather than a currency in transactions.
