Bitcoin's market share has fallen below 60%, hitting a six-month low. At the same time, TOTAL2 and TOTAL3 are rising concurrently, as the market anticipates a new round of 'altcoin season' brewing.

Vice President Vance: Soon, 100 million Americans will own BTC) Bitcoin's market share (BTC.D) reached a four-year high of 66% in mid-June this year, but has been continuously declining recently, falling below 60% today (10), marking the lowest level in six months, dropping to 59.97% before the deadline, a decline of over 3% in a week. The break of this key level indicates that funds are starting to seek higher Beta target markets, and more voices are seeing this as the starting point for capital rotation into altcoins. TOTAL2 and TOTAL3 are rising. Notably, the total market cap excluding Bitcoin (TOTAL2) jumped 11.94% in a week, currently reaching $1.56 trillion; the total market cap excluding Bitcoin and Ethereum (TOTAL3) also increased by 8.58% during the same period, surpassing $1 trillion. This shows that while funds are leaving Bitcoin, they are quickly entering other currencies, coupled with the recent continuous net inflow of stablecoins into exchanges, providing 'ammunition' for altcoins to surge. The total market cap excluding Bitcoin (TOTAL2) presents both opportunities and risks: investors need to be cautious in their layouts. However, despite Bitcoin still fluctuating at high points, the author wants to remind investors that if BTC does indeed undergo a significant correction, the decline in altcoins will likely be even more severe. When sensing the market atmosphere is off, be cautious of the 'pullback risk brought by high volatility', and avoid blindly chasing highs. Moderately diversifying, setting profit-taking and stop-loss levels, and dynamically adjusting positions are still necessary practices to navigate through volatility.
