Those who bought at $70K, succumbing to FOMO, are already in the red. After the weekend, the bears might start hunting for the bulls' stop-losses. I've seen analyst forecasts predicting Bitcoin could fall to the $50K mark.
A time will come when those who bout at $70k will feel extremely happy that they were able to buy bitcoin at that price. In bitcoin you don't lose provided you don't just sell your bag in the red. Remember there are people who bought above $120k, and they are still alive. Now compare them to the people that bought at $70k. You can call it fomo or whatever, but you should know it's very difficult to catch bitcoin at the bottom of the every dip. For me $70k entry point is a bargain price considering how high bitcoin has done before and it's still projected to do more. Just don't sell.
