A very kind person explained what you are asking very simple to me.

20 years ago, in my country there were almost no money. People were spending all their salaries on food (2 loafs of bread, 1 kg of potatoes, etc). There were no money for paying utilities, going to another country, etc.

Every day I had to read the supermarkets food prices from the junk mail. Every price was low and every food price was lower with 10% , 16%, etc than it should be. 

In 20 years, because of these leaflets with food prices, the price of food has increased 100x (100 times) in my country.

This is the reason for the bitcoin bull run. The food prices have gone up (have increased) with 100x in the last 20 years, and they will continue to increase in the next 10 years because everyone in this world reads his junk mail, where the food prices go up every day.
