A very interesting question: will the Ethereum coin become a store of value? Personally, I believe that for Ethereum to become a store of value, a coin needs to be stable, in which case a preservation option could be considered. But at the moment, the Ethereum coin is unstable and can fall in price at any moment. And then all savings will simply be lost. Perhaps, in the near future, such cryptocurrencies will appear, with the help of which it will be possible to make long-term savings. Many more interesting discoveries in the world of cryptocurrencies await us.
Isn't it already? I mean it doesn't need to be stable, if it is stable that means it is not store of value at all, for it to be store of value the price needs to increase faster than inflation so that we wouldn't have it go down in value. A house that worths 1 million dollars today would worth 2 million in 10 years, you need ethereum to do at least 2x during that period to keep that value.
So, being volatile and increasing in price over long period of time is one of the ways to be really profitable in the crypto world to keep ethereum, plus there will be staking it in the future as well (and I guess it started a bit in some ways) so you will not only hold ethereum but also make ethereum profit from holding it as well. I believe it is one of the perfect examples of store of value and it will continue to be so in the future as well if eth 2.0 provides to be a wanted project.
