The cryptocurrency market is witnessing a clear shift as capital begins to flow away from Bitcoin and heavily into altcoins. The total market capitalization of cryptocurrencies (excluding Bitcoin – TOTAL2) officially hit $1.5 trillion on Friday – a major timeframe resistance zone last tested in January 2025.

While this may be an area where the market pauses or corrects slightly, the long-term trend still favors a strong breakout past $1.5 trillion, aiming for the historical peak of $1.72 trillion. If TOTAL2 closes the monthly candle above 1.51 trillion, this will be the highest positive closing in the history of the altcoin index.

💰 Stablecoin Boom – Driving Force Behind Altseason

According to Cointelegraph, USDT and USDC balances on Binance hit a record high of $31 billion in June 2025 – showing that a huge amount of capital is still waiting. This week, Binance and HTX recorded stablecoin inflows of $895 million and $819 million respectively, showing that the wave of liquidity is returning to the market.

On Wednesday alone, more than $2 billion in stablecoins (mainly USDT) were deposited on major derivatives exchanges, indicating a surge in leveraged sentiment among professional traders. The continued printing of USDT by Tether Treasury further reinforces the story of institutional demand and a willingness to accept higher risks.

While Binance still leads with over 55% of global trading volume (over $8 billion/day), the flow of BTC from whale wallets onto the exchange has decreased by $2.25 billion, meaning that Bitcoin selling pressure has weakened, paving the way for cash flow to shift to altcoins.

📈 TOTAL3: Altcoin Market Excluding ETH Heading Towards $5 Trillion?

TOTAL3 – the capitalization of all altcoins except BTC and ETH – is currently only at $1 trillion, but according to many analysts, we are only in the early stages of an altseason supercycle.

An anonymous analyst named Mags argues that altcoin cycles usually take place in 3 distinct phases:

  1. Escape from prolonged accumulation zone

  2. Gradually increasing in trend

  3. Parabolic rise – where the majority of huge profits appear in a short time and leave latecomers behind.

🔍 Altseason Index Still Has Plenty of Room

The Altseason index shows:

  • The 30-day index has exceeded 75, confirming that the shift of funds to altcoins is underway.

  • However, the 60-day index is still quite low, meaning that not many altcoins have outperformed BTC for a long time – this is a clear sign that altseason is still in its early stages.
