I will begin by saying that what I write here is based on my opinion and my experience.

I heard about Bitcoin about nine years ago.

At first, the idea of making money from the "air" seemed to me like a dream come true, and I decided to try coin mining by myself, after a few days I noticed that the computer was getting slower every time I ran the mining software, even though I had a relatively strong computer for that period (i7 processor and geforce 295gtx. I'm talking about nine years ago remember?! ;-) ) At that moment, I realized that there was no such thing as money from the “air”, and that for Bitcoin mining/production required a great deal of resources, such as electricity, time and especially patience.

After the previous understanding, I understood another important thing that no matter what you offer for sale once it is relevant enough to the other will buy it, no matter whether it is an item, idea or service.
In evidence, I will give the familiar example where a person has on average items that do not need a value of $3,000 that could be sold on eBay.

The combination of the two previous understandings made me realize that people love to embrace
new technologies and to be part of something big.
in many cases people will be willing to harness money or worth money, especially if the same thing invested in a lot of energy and resources.
So right now Bitcoin still can not be paid in many places and there are still no notes or coins of any digital currency and it is easier to adopt something that can be touched and felt , but the future is already here
