Panic selling is what draws the price of Bitcoin so down to the drain. Any event which leads to panic selling of Bitcoin can be considered as a contributing factor. The news of a hacked exchange site, false news from governments, banks and the media, a Bitcoin advocate country later banning Bitcoins etc. All these factors contribute to the fall in price of Bitcoin on the market.
Dont just focus on panicking situation because we all know that manipulation is happening in crypto community specially in market movements.
We must not forget that panick is a normal reaction of investors everytime they see that big amount on value is getting into their coins.thats why i believe that this is the right time that small investors like us must get one stand tp hold so e can maintain the strength of cryptocurrencies
