Yes, Bitcoin is falling quite hard, this makes a panic sell. The reason maybe is because the hard fork of Bitcoin Cash so people sell their Bitcoin and buy Bitcoin Cash and it caused a panic sell. But, this will normal again and Bitcoin will go up again. We will see about it.
Hardly hard fork bitcoin cash, which is scheduled for today, was not the cause of this fall of bitcoin. They knew about the tough plug for a long time and hardly on the last day everybody started buying Bitcoin in cash. Although this could also play a role, there is no bad news about the cryptocurrency relation. This fall in the cryptocurrency market will play a bad role, it seems that the market stagnation will last for a long time.
