Some people refuse to take profits when their coins and tokens are surging so high.
Because greed let people keep on waiting for higher and higher value for there coins and end up selling at dip.
Since price can’t go up all the time.
I think waiting for tokens/coins to go up is not greed but HODL. Because those who wait for better results are still normal actions even though the results are even worse. In Cryptocurrency, Greedy in my opinion are those who break/Steal into wallets person or a project which ends up being a Scam person.
