Someone keeps saying that bitcoin was hacked, that someone is responsible about the tradings happening and the amount of volume of bitcoin. But might the main reason is the government releasing bad news abiut bitcoin.
Bitcoin was hacked? I hope you doe not believe whoever said that. But the fact that you stated it here without contradicting the claim would indicate that you somehow believed that claim. Bitcoin is not vulnerable to hacks. Bitcoin is decentralized and that protects it from hackers. The concept of hacking is targeting a single point in a network in order to access the main server. But since Bitcoin does not have such, then hacks are off the table.
Hacking is also a big problem for bitcoin investors and this problem may not be solved till end. New investors scare to put their money in bitcoin because there is no place where they can claim their money. To avoid this thing many people do not invest in bitcoin and thus the demand for bitcoin becomes low which is one of the reasons of decreasing price.
