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?
In my opinion, there is no need to strive to ensure that ethereum mainly acts as a store of value, as Bitcoin does now. The main purpose of a decentralized cryptocurrency is to be an alternative means of payment to the current payment system. However, any type of money includes all functions, including a store of value and value. But the function of the means of payment must be decisive.
I don't think there is a real threat for ethereum to become like Bitcoin. Thousands of tokens have been created on the ethereum platform, the movement of which requires payment with this coin. Therefore, there will always be an ethereum movement.
There are no barriers to using Ethereum for savings like Bitcoin. ETH today is not only fuel for its ecosystem, but also a rather profitable asset for investment, a means of payment and, of course, a means of savings. If we talk about cryptocurrency as a reliable storage, then even bitcoin cannot act as a storage today, while there is a huge volatility of these cryptocurrencies. But the more large investors increase the capitalization of Bitcoin and Ethereum, the more the percentage of their price stability will become.
