The analysis suggests that Ethereum (ETH) is currently following a price trajectory similar to the S&P 500 (SPX) in 1989-1990. The first chart shows ETH potentially heading towards a significant dip below $2,000 in early 2025, aligning with the historical SPX pattern. The second chart, updated more recently, indicates ETH has closely mirrored this historical path, implying a potential for further downside before a recovery, which could impact the ETH/BTC ratio.
