If they're claiming about the owning of bitcoins, then ask them to control the price and the value. I've firmly believed only the owner of bitcoin can stop its value. We all know about Satoshi Nakamoto. First, he belongs to Japan while Craig is from the United States. In the world of bitcoin, everything is a fraud, and you can not trust anyone easily.
If the owner of Bitcoin can stop its value, then it wouldn't be decentralized anymore. This would make Bitcoin no different than the banking system of today. Only true decentralization will allow Bitcoin to live for generations with or without its creator. There are so many people claiming to be Satoshi only because they want fame and fortune. The real creator is either dead or simply hiding in the shadows in order to avoid being caught by the authorities.
I'd say it's best to never know who Satoshi is or who he/she really was, since it would do more harm than good to Bitcoin. The community is what keeps a blockchain network strong, not a single person. Eventually, the mainstream media will become tired in their search of Satoshi, as they focus on other important things. As long as Bitcoin fulfills its purpose, nothing else matters. Just my thoughts

With this alone then you could really say that it isn't decentralized after all and that would surely crash out Bitcoins value in the first place.There are lots of people who had been proclaiming
that theyre Satoshi but no one had able to prove it out and they do know on how popular Satoshi is speaking off Bitcoins creator then they are just simply using that for their own intent.
Thing here is that the entire community does know on whats real and whats fake and Satoshi wont really easily be coming out for that reason.
