whatever you think ETH has can be achieved by another project especially if a project is backed by a big tech company like facebook promoting their own L1 token. there is nothing in this industry that sticks to their first plan. XRP can turn into a L1 project any time or even the USDT which can turn into a more suitable platform for developers.
like you said LTC used to be silver. maybe ETH also turn to Lithium one day and silver will be something else. what matters is the community behind it.
I agree, especially since Eth is currently facing many difficulties due to the impact of L2, and the ETH token price is very low in the market. Things get even worse when investors look at the ETHBTC chart, it feels like ETH has been forgotten in the market and given way to other L1s like Sol, Sui, Bnb, Trx...
If choosing assets to hold for decades, I think BTC will always be the top choice. Investors can also choose a few top coins with great value and potential, for me, ETH still deserves to be trusted, because it is still the crypto queen or digital oil.
