What Charlie is saying is that the price of Litecoin is all based on the community. Bitcoin had a massive drop just as Litecoin had in the past. With more people becoming aware of crypto, too many people are throwing their money into Litecoin because of the hype. They don't understand what crypto is in general nor what Litecoin is in specific. So he's essentially saying to not invest what you can't afford to lose. Crypto is volatile and coin values can drop. The drops aren't rare.
