That is the same what Chinese government is doing. Libra has exactly the same idea of centralisation with blockchain and in my opinion it is an important step towards the mass adoption, even if we would sacrifice decentralisation at the end.
if leaving the word decentralized means that it's not an actual blockchain technology, Bitcoin is already famous for its decentralization making everyone want it,
It's and you are wrong about that. sometimes the decentralized can be part of the blockchain but you must consider there was another chain that called a sidechain which is really centralized.
that depends on what will be the purpose of the blockchain itself. If that will be used as a public blockchain and decentralized is a must caused by that puts transparency at the top of the blockchain.
but you guys must understand if the main intention of this thread is about telling use if roubini was a promoter for the centralized banking of the digital currencies.
