One of the reasons I'm sure among others are panic selling, but we must know the fluctuating of bitcoin price and still easy to be influenced by many things, didn't close the possibility it will moving back to the height again. I'm sure the current price drop happens, it's just temporary and would be moving back upwards, I'm sure it is!. So well I just suggest don't too worrying about that, it's good we take positively things and deal with the situations with calmly.
That fall in the prices does not look like an alarm,if the price fell again until the $8K then would be an alarm signal there is also the option that the price remains stable between $15K or around that would also be a good sign,and if,such as some people say,the market is cyclical,then there is no reason to really worry about that.
Agree, we shouldn't be alarmed by a small decrease in the price of bitcoin because this is just normal due to volatility. Other people are starting this thread about the decrease when it was not that big and compared to those previous dump, this is nothing. But if the price continue to decrease after few days then you may be worried, just don't overthink too much to avoid panic selling and hold because eventually the price will rise again.
