When we are at Extreme Greed you need to be taking some profit off the table. Most people in crypto fail to keep the money they've made. They either sell too late or they selfishly watch all profits fall back to zero.
If you are a trader and you don’t know when to take profits, then you are hardly going to make profit from trading, because you won’t leave the market when you are suppose to leave, you will want to get more profits, till price of coin start dumping before you will start struggling to sell. Some will lose all their profits and will still lose some of their capital, just because they don’t know when to sell, and mostly we shouldn’t be greedy, always take profits even if it’s small, their is no crime in taking profits. But if you think your profits is too small, and you keep on waiting for it to increase, things doesn’t go as planned always.
Greed has no room in trading.
