Once it become centralized he will reveal that in public automatically.
How it would be possible. Really I could not understand how bitcoins will get chances to become centralized. Even some countries legalizing bitcoin system or adopting bitcoin payments as their regulated currency, I believe, those will not affect any of bitcoin concepts of being decentralized.
Maybe he is best friend with Satoshi Nakamoto told him that he will come out when bitcoin becomes centralized! Lol! Or maybe Satoshi Nakamoto talked to him in his dreams! Hahaha. He is really very funny!
Close friend maybe? or stoles of some ideas of him? we dont know. haha i dont know if when or it will be happening it soon that thing "Centralized!" haha i didnt think of it and i dont why? hahaha
