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.
It is important to set profit targets before investing in Altcoins to avoid greed. If you have set a profit target of 2x, 3x even 5x we can sell it when our target is reached. Doing hold and whatever profit we get but we don't want to take it, in my opinion this is not greed, meaning that profit is not a benchmark against us cryptocurrency lovers, but very few people like this.
