Do you think Ethereum has potential to become store of value? Why or why not?
Yes.
It's becoming into that point because people wouldn't want to sell it because of the fees. By looking the past prices of it, this can be said that it's one of the good store of value that we have.
But I agree that if the ETH devs won't find a way to solve the current problems that we're dealing with about high fees, it's classification of being a store of value would be gone gradually.
I have not checked ethereum for a long time, we know that there is a limit in the amount of bitcoin that it is going to exist at 21 million, but that was not the case with ethereum, has this changed? If not then it has no chance of becoming a store of value as no one is going to trust their funds for the very long term in a coin with no limit, but if this has changed at some point during the updates of ethereum then this could help it to eventually become a store of value.
