Eth vs Btc: What is the reality?

So eth just hit its highest weekly close since 2021 at 4,300. The ETH/BTC ratio doubled from its April low, and suddenly everyone's asking if Bitcoin is losing market share. but whats the reality?

i caught two takes today that got me thinking:

first, Samson Mow argues the recent eth rally is fueled by bitcoin holders rotating capital into eth for short-term gain...only to dump it once prices get high enough and shift profits back into btc. he calls this the “bagholder’s dilemma.” current eth/btc ratio is around 0.036, double its april low, but he warns eth faces a sell-off once it hits key psychological levels

Secomd, Willy Woo called Bitcoin the "perfect asset for the next 1000 years" - and looking at longer timeframes, the fundamentals remain unchanged. Bitcoin's market cap is still only 11% of gold's $23 trillion, meaning we're far from complete adoption.

The real question isn't whether ETH can pump another 12% to hit its ATH. It's whether Bitcoin continues building toward becoming a world reserve asset. And for that to happen, we need way more capital flowing in.

in short term flows, eth sees spikes from traders chasing yield, but profits often rotate back to btc

in long tem confidrence, btc remains the default store of value

in short, btc isn’t losing its dominance, capital flow dynamics shift over cycles, but fundamentals still favor bitcoin for many institutions. eth can rally within those windows, but its staying power depends on sustained narratives, not just hype.
