as long as they don't ban bitcoin from big countries such as france i think regulation should just be fine because i notice when there's a new news regarding regulation of bitcoin there are some small dips but it can catch up easily later on unlike in a total ban where correction on the market will happen instantly.
There is no bad thing about the regulations for the cryptocurrencies because it is just normal for the crypto to experience some regulation since it is not that controllable by the government so they are only depending on the regulation to be able to control the possible bad scenarios that might happen when the abusive users came to bitcoin.
