I need your opinions that, if Bitcoin is been centralized can other cryptocurrencies survive .
Supposes bitcoin is centralized I do believe other cryptocurrencies will survive. But currently, even though Bitcoin held firmly its principle, any other coin are not having any decentralization that is close to Bitcoin. In fact, some of them only use the word decentralized as a buzzword. So the reality is that other cryptocurrencies did not maintain that aspect as a priority. Given that, if Bitcoin somehow loses its credibility, I don't think there will be something wrong with the sustainability of other cryptocurrency projects.
