I was checking greed and fear index in coin market cap website and I noticed that there is big reduction on the fear because until last week it was more than 80 but now it is summer around 65. My understanding is that when there is less fear it means people are not buying much because possibly they are waiting for even better prices a maybe some thing else they have in the mind which is the situation in the Crypto market currently.
So when market crash happens, try to buy coins that are good with fundamental
That tends to happen on big selloffs. The risk level in the minds of investors is reduced with lower prices. Of course, much of the fear is from those who believe a crash is upcoming.
The greed comes from the "buy the dip" people.
Eventually the market determines who is right.
