I have seen recent some fudds and market reaction . Even normal FUD or Fake news also makingHuge Bearish trend in Marketcap . Recent South Korea , India Regulation Fud complete fake news made lots of impact so that market reached 700 Billion to 500 Billion. Yesterdays Binance Fud (Fake News)again Reduced 100 Billion . Whats happening everyone are becoming too greedy so that they cant even check for actual fact .
The market is definitely volatile and investors expect substantially higher returns compared to other asset classes. That is natural, because higher risk investments are expected to give high returns. I wouldn't call them greedy for that. They are just investors, with high risk appetite. There are others who try to gamble in the crypto markets and buy/sell on the latest fud and positive news articles. You cannot really attribute rationality to their behaviour.
