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.
Poor are ready to take even a small profit. They usually are not greedy. I would say, those who have enough and are not depend on the return out of what they have invested in, will hold for long term to see a reasonable profit. Its not that they are greedy but they are confident on the coin they have invested in. They are much confident on crypto market and its growth. They have seen it from the time Bitcoin came into the market. As long a crypto coin is held, the value is going to be double and the profit is going to double.
