The main reason why, as a non-techie person but as someone who has a fairly good grasp on economics and philosophy, I am all-in on BTC (in terms of storing my long-term wealth), is that I GET IT.
Unlike cryptoassets that want to "improve" on BTC, which I just don't GET if I look at them from the same perspective: is this a sound store of wealth? And it doesn't look like it.
The question then becomes: if they're not a sound store of value like BTC is, what are they supposed to DO?
I know the cynical BTC-only answer already ("They're all scams"), but I think it is partially true only. Some, well, most "crypto" are outright scams, there's no doubt. But I'm ready to give the benefit of the doubt to some projects, even if I KNOW that the result is going to be the same: centralization and, thus, not a sound, safe, permanent store of my financial freedom.
Having stated my good will then, to reiterate: what is ETH supposed to DO?
