After the closing price of Ether exceeds a certain Gaussian channel threshold, the total market capitalization of altcoins (minus ETH) skyrocketed by 1,400% and 200%.

Key Points:

* Ethereum has reclaimed over 100% rebound to a key level and triggered the past altcoin season.

* If Bitcoin's dominance experiences another drop post-halving, the market cap of altcoins could soar to $15 trillion.

* Despite bullish signals, ETH remains fragile with a supply close to the cost basis at $123 billion, posing a risk of turning unprofitable.

Ethereum's native token Ether has reclaimed a key technical level that historically precedes significant price increases, marking the 'beginning' of several market cycles over the past five years.
