Now hypothetically: Bitcoin goes down the drain and a new cryptocurrency takes lead as number one. Wouldn’t this mean that all miners would switch from mining bitcoin to mining the new currency? Ergo, the new cryptocurrency would still be controlled by Chinese miners. Given that the new cryptocurrency runs stock markets, bank transfers, smart contracts, basically the 2020+ world and no one wants one single country controlling the majority of hashing power, this would force governments to settle for agreed hashing quotas and regulate that cryptocurrency. Or the banks will create their own - controlled - cryptocurrency. So basically, is there any solution, where not some entity controls the crytocurrency in the future?
