Market conditions reminiscent of previous altcoin booms have resurfaced, as noted by trader Merlijn. A decline in Bitcoin's market dominance and a reversal in the ETH/BTC ratio are key indicators suggesting a potential shift of capital from Bitcoin to altcoins. These signals have historically preceded altseasons, notably in 2017–2018 and 2020–2021. Despite these developments, retail investors have often overlooked such early signs in the past.
