Nothing is impossible in crypto industry. I strongly believe in the potential and capabilities of etherium to beat bitcoin someday and become ranked 1 but that will happen after several years. Eth can value up to 10k usd only after beating btc.
Bitcoin and etherium are very close competitor and now it look possible to beat bitcoin.
But if we see in the deep again, etherium like impossible to beat bitcoin since it has low market cap and also much more supply compare with bitcoin.
