Are cryptocurrencies a 'pump and dump'?

Are cryptocurrencies truly just a form of "pump and dump" schemes, where investors buy up coins to artificially inflate their prices and then sell them off at a profit, leaving others to hold the bag? Or is there more to the story? It's a valid question to ask, especially given the volatility and speculative nature of the crypto market. But it's important to note that not all cryptocurrencies operate in this manner. Some projects have legitimate use cases, strong communities, and a roadmap for long-term growth. It's crucial to do your own research and due diligence before investing in any cryptocurrency, to understand the project's fundamentals and assess its potential for long-term success.
