Yes it could be a big win for crypto but Bitcoin and other decentralized crypto projects don't need any centralized help to stay alive, this will only create for awareness and possibly more adoption, crypto will still survive without any help
Actually BTC needs proper regulations to go mainstream fully, regulations are from centralized authorities. In as much as centralized authorities cannot control crypto, they still have a role to play wrt acceptability. I really like the news put up by OP, Bitcoin being recognized as money by a government body is a good one.
I guess so because, with the government's regulations, that can help people to invest or use crypto without worry because they know that the government can protect them if something worst happens in the future. Besides that, maybe the crypto can grow fast than before because the government can watch and know if the project is trying to scam people.
