Remember ADA (Cardano)? Once the third-largest cryptocurrency by market cap. At its peak, its market cap soared to $101 billion, and countless people believed it would become the "Ethereum killer." But now, ADA has just hit a new 5.5-year low. From its all-time high, it has already plunged 93.4%. Many people think the bull market will bring all coins back. But the reality is: Most altcoins will never return to their peak. The harshest truth in the crypto market isn’t the drop, but being forgotten by time.
