The altcoin market cap has retested the $1.55 trillion neckline following a confirmed breakout from a four-year cup and handle pattern, as analyzed by Gert van Lagen. This technical formation on the 2-week chart suggests potential growth toward $3 trillion to $6 trillion if the neckline holds. The CMC Altcoin Season Index currently stands at 67, indicating continued strength in altcoins and a market rotation away from Bitcoin. This development highlights the growing interest and investment in altcoins as traders seek opportunities beyond the leading cryptocurrency.
