This is just my opinion, but I don't believe Ethereum will ever be a store of value, and prepared to give some reason why I think so. Feel free to tell me I'm wrong or if you agree in the comments down below.
No Consistancy
One thing you can almost guarantee is that how many Bitcoin are generated with every block, how fast the blocks are mined on average, and the total number of Bitcoin produced will never change. No matter how many people try to fight, hack it, or change it, Bitcoin still marches on with very few changes since its creation.
On the other hand, you have something that is always trying to improve, coming up with something new, and having brand new projects built on the platform and that is Ethereum. From ICOs, to DeFi, and NFTs, there is never a dull moment on Ethereum.
You also have major changes, such as the switch from POW to POS and the EIP to change Ethereum into a deflationary currency, these are major changes, and I haven't even mentioned the hack on the DAO. How can something be a store of value if 4 years from now a new EIP comes out to switch Ethereum back to an inflationary currency, change the hard cap, or set/remove a hard cap.
Usage on a Platform
You want people to use Ethereum instead of just hodling it. As more value is created on top of the Ethereum network, the more people are going to want to use the network, the more Ethereum they will need to interact with the network.
If no one is using, no one is building, so what's the point of owning any Ethereum and developers move to other platforms to release their projects. I don't want to regret 10 years from now that I spent $10 million on Ethereum gas fees and instead of just holding Ethereum.
In Conclusion
I don't want another boring coin you just buy and hold and take a risk and maybe be some interest in a Cefi or Defi platform. I want to play on the cutting-edge playground where projects are finding new ways to create value in crypto.
This definitely has some risks, but I'm ok with that. I have my store of value I'm invested in and I want my project that could, even with inflation, carry my net worth to the moon.
Finally, would love to know what you think down below. Is making Ethereum deflationary just a bull market tactic, a move to try and steal some value from Bitcoin, something that is good or bad for Ethereum.
