Globally, the economy is not improving. It has become really much better in most of the developed countries that are located in Europe, and North America.
There is a crisis in many countries. I do not think that the economy of most of the countries is improving. The life level of billions is still very low - people are trying to survive under these conditions simply.
So this is what everyone who is in the market want. The rise and revival of the economy, particular the crypto economy from which so many people are expecting big outputs. Rise in the market will no doubt help the investors make more money.
