One of the reasons of this is the inflation: it is a kind of regressive tax, this tax is paid mostly by the poor because they loose their savings, while the wealthy keep their savings not in money but in assets.
Isn't the reason that rich people invest in various assets simply because they have enough money for their daily lives and can afford other ways of investing? 
Give a poor person bitcoins or other assets, and the first thing he will do with them is sell them. And I don't think we need to condemn him for this, because firstly we need to ensure that basic needs are met, and then we need to think about investments. Moreover, Nvidia shares or cryptocurrency cannot be used to pay for utilities, for example.
Then , for those who have spare money to invest, endeavour to invest in bitcoin ,more especially for a long time.Bitcoin is a digital asset that can not be underated, is something that anybody can invest to change his financial story.
It is true that most times, the leaders make policies that favours them mostly, but we can not depend on them all the time. As individuals we have to do our best to help ourselves, because looking at our leaders and politicians will cut off our expectations. So let us endeavor to do the best we can to invest and surely our financial goals will be reached.
