 Yes, so what do I think about inherent mining or other centralization tendencies like access to the developer commit or To other things I think we forget that Bitcoin has actually become a hell of a lot less centralized in The eight years that it's existed. So in the beginning there was one developer his name was Satoshi Well, not his real name, but still and there was one miner and his name was also Satoshi So all of mining and development was centralized under one person, right today if you look at the core It's gone from a grouping of about a dozen people three years ago to more than a hundred active developers Who are working continuously some of them full-time if you look at mining? You know people say oh, it's centralized in China China is a massively decentralized country and so even within China It's actually massively decentralized there. How many miners do we have today compared to how many miners? We had three years ago So the trends even though they seem more centralized are actually more decentralized I'm not worried and part of the reason I'm not worried is because there is constant pressure in the opposite direction to Decentralize and this is a self-correcting system if we centralize too much The system will become vulnerable to attack and then it will be attacked and then it will either be forced to Decentralize or it will die and we'll build a better one next time which is more decentralized. This is a very self-correcting thing So I'm not particularly worried about it
