Speculative cryptocurrencies are digital assets with high volatility and uncertain long-term value. They are often driven by investor hype, social media influence, and rapid market fluctuations. Many speculative coins lack strong use cases or real-world applications, making them riskier investments. While some investors are drawn to the potential for quick, substantial gains, the unpredictable nature of these assets also brings significant risks, including the possibility of losing the entire investment. Popular examples include meme coins like Dogecoin or Shiba Inu.
