There is no such thing as a decentralized environment. The blockchain is not one either. Once the bow is rounded, the blockchain depends on your power provider. It, in turn, draws its energy from the physical resources of the planet. For the maintenance, construction, and research of energy sources, people are employed who need to be nourished, require food and a roof over their heads.

Cryptocurrency is therefore neither particularly revolutionary nor decentralized. The creation of this currency is basically a copy of the creation of Fiat money, all zeros and ones in the computer matrix. Krypto is Fiat's little sister and both are not particularly philanthropic. Social media is basically put on top so that making money makes sense.

The experiences that people make in their physical world are projected into this space and taken out into the real world again. There are no real experiences to make here because they are purely mental in nature.
There is nothing decentralized in the entire existence of all existences on this earth. Nothing at all.

Besides, this is risk trading. None of this is safe. To be on the safe side, this should not be the subject of speculation. But what is the nature of this platform.

As long as we need exchange platforms in order to participate in the crypto market, we'll be still not able to fully enjoy all the benefits decentralized environments provide.

Correct. The question is if we should enjoy all benefits without physical effort. I am not against all technology. But as we are provided with electricity and don't do anything physical to get it the question arises why that should be the case further on. I am imagining myself producing the needed energy for my laptop by a bike which generates the energy for my device so my guilt feeling of sucking up electricity is compensated somehow more environmentally friendly. Just to give an example how I see this world I live in.

I hope you don't mind that I expanded your topic a little bit.
