The issue with BTC is something like ETH that has potentially greater value longer term.
The issue with ETH is that there may be another competitor/layer2 that wins in the long term.
Anyways, one should have both currently, but I think being a maxi only goes so far.
I own btc and not much eth, but I do own Eth erc-20 tokens that are worth 6-figures $
I also own tokens on the Bsc blockchain that are worth 6-figures $ amount
There is a robust and smooth linkage between Bsc and Eth blockchain which is symbiotic but benefits much more so the Bsc side to the point that can be argued is parasitic
I do not see Eth and Btc as competitors, If Btc goes up 100% and Eth goes up 500%, I will be very happy
I honestly wish for Eth to succeed. I have vested interests on the success of Ethereum
Even Michael Saylor has acknowledged the importance of Ethereum and its defi ecosystem which is valuable to the cryptos ecosystem growth and future
Bitcoin is competing more so with gold as a scarce asset, hard money, store of value, pristine collateral. I would recommend "The Bitcoin Standard" book for more clarity on this Bitcoin value proposition
Ethereum may start to compete in that with the EIP-1559 upgrade, but that is not Ethereum's main focus. Ethereum is a robust smart contract platform and its value is cemented
