People, I hope more people understand me..

The last month seems to be the market is so unstable. It goes up and down. Is this a sign of a coming crash? Where we read positive news? These are the signs of a huge crash, because the cryptocurrency is not accepted by the ' elite '?
A few days ago, a South Koreas regulator is founded dead in his home. A accident or a murder? How knows?

In addition to this, I know that the cryptocurrency worldwide is often used by large companies/Governments.

Can anyone understand my feelings? If so, why? If not, why not? I am worry too much?
