Who the fuck told you that bitcoin is a business? Blockchain is a technology, existing today all because of satoshi, the idealogy behind and the way people use blockchain is what makes it better than previously used technology. I wouldn't say that blockchain is a business, but its the backbone for certain businesses and if utilized properly can do wonders. People say quantum technology is better than the blockchain technology, but quantum is still under deep study. There are not many leads but that technology is powerful. Until quantum becomes the new world aspiring technology, blockchain will probably will go big. Blockchain can be used for almost anything, but people are more busy utilizing it for scamming others and not focus on world's economic and overall development.
