Of course it will be a positive news in favor of Crypto world in which the bank and the crypro are working together towards prosperity. The best news regarding banking system supporting crypto currency is JP Morgan in which they will fully adapt Bitcoin and the blockchain technology therefore with these development the future of Crypto currency is more secured.
This is not about the bank and crypto working together, this is about the government trying to see how they can gain control of the space as much as possible. However, this is a decentralized space and unless they want to start bringing up their own centralized currency, a decentralized space naturally removes a third party and that makes it easy for anyone to control the way they spend irrespective of the banks involved. Banks can decide to come in whichever way they like to be able to adapt to the space.
we don't need a central bank for cryptocurrency, this is not going to happen even government will take over in this market because for sure no one will invest. This market is created and meant to be decentralized, its ok to have some regulations but never to control by any government. Crypto central bank is just a dream for every government, we should not support it.
Asides from not needing it, it is not even necessary at all. We are talking about decentralization here, and there is no way having a central bank for the whole cryptocurrency can work unless they just are not getting the picture yet.
Yeah, banks will adopt the technology, they will create their own coin which will be centralized as there is no doubt or two ways about that, and for that reason, it will still not be different from the fiat we already have in play, except that there would be some level of transparency which is what the technology brings.
