How would we know if the coin you are talking about is a mere pump and dump coin or a legit one? You did not mention the coin itself. There are a lot of coins in the market right now. And the majority of these are simply shitcoins. But even shitcoins could make you rich. For as long as there is volume there will be hope of making something out of it. Be careful though if there are huge pumps happening, there might also be a huge dump happening almost immediately after it.
