Meme coins are a type of cryptocurrency created from internet trends, lacking clear technological value. They often experience significant price increases due to community and celebrity effects, such as Dogecoin or Shiba Inu. While attractive for quick profits, meme coins are extremely risky due to large price volatility and susceptibility to manipulation. RSI and MACD are often strongly distorted with this type of coin, making technical analysis less effective. Investors need to control their emotions, manage their capital well, and should not go "all-in". This is a playground suitable for those who accept high risks.
