Decentralization can only be global in part. Perhaps it will be for some products and areas of activity. Cryptocurrency has gone very far just to disappear.
Nowhere cryptocurrency will not disappear. This process is already running. Most of the current projects either disappear or transform into something else. But the cryptocurrency technology itself and the idea of decentralization came to us seriously and for a long time!
I also agree,,,that the crypto industry will exist for a long time, the capitalization of 12 106 550 244 190 dollars at the moment, just will not allow the crypto to disappear
