For me Ethereum is the second trusted coin for long hodl next to BTC. My confidence and trust in BTC is
80% and 20% in ETH. This is how I split my long holdings.
Ethereum and Bitcoin are both large giants in the crypto world but neither one is invulnerable to a takeover by some young upstart. See how ETH lost 2nd place to XRP, even if only temporarily. It may not be XRP, maybe some other coin will bring the upset and upheaval to the crypto world. Can you imagine a crypto world with some other coin at the figurative helm?
