Although mainstream attention is still focused on Bitcoin, a set of data is quietly hinting at the prelude to a market shift—the altcoin season index is currently only 29/100, indicating that market liquidity is still concentrated in BTC. However, this precisely suggests that altcoins are undergoing a 'silent accumulation period', much like the quiet before the big market movements in 2021.
According to the combined charts from AMBCrypto and analyst Alphractal, whenever Bitcoin surges and then enters a consolidation or slight pullback, altcoins welcome a critical breakout point. Currently, BTC has repeatedly broken through psychological barriers, and its momentum seems to be waning; the 'countdown' for the altcoin season may have already started.
Will history repeat itself? June is often the 'launch month' for altcoins.
Looking back at history: In June 2021, altcoins exploded, market sentiment soared, and multiple coins achieved tenfold or even hundredfold growth. Now, in June 2025, some signals are appearing again:
The Altseason line has fallen into the Bitcoin season range (green box).
23% of altcoins have outperformed BTC.
$3.8 billion in capital flowed into the crypto market in Q1, setting a new high since 2022.
These phenomena are all hinting that the 'accumulation period' is about to end, and funds are brewing a new round of 'rotation' market.
However, don't be too optimistic: liquidity is the biggest uncertain variable.
Although there have been some local altcoin launches in the market, such as SOL and HYPE reaching all-time highs, the market overall is still in a wait-and-see and low liquidity state. If external capital cannot be attracted again, the 'rebound' of the altcoin season may only remain among top assets.
It is worth noting that the true 'Altseason' has only erupted once since 2019, in 2021. Therefore, do not blindly expect a full bull market; instead, focus on strategy and tool selection.
