It's just time for other powers to get heavier involvement. I doubt major powers such as Russia or the USA would simply let China centralize BTC. It has deeper roots in our companies than that. Maybe, they're just waiting when to send some packages to Chineese miners 
USA joined the rally already if you know the news about them making coinbase audit all the transactions made from the past years, it is just showing that they are interested to bitcoin. And as far as I know, Russia is near to acceptance to bitcoin.Its been nearly one year to the start of this topic till now Bitcoin is living and its been living prosperously. USA, Russia, Japan and many other strong technological countries are showing more interest in BTC and trying experiments socially. BTC will definitely live for at least 10 more years.
So you are just speculating that bitcoin will be only alive for 10 more years? Bitcoin will certainly live for so many years as long as we are here that are users of bitcoin then there's no need to worry about it. Bitcoin is stronger right now and it will going to make it's strength broad just like what you had mentioned because that will be the reason.
