Bitcoin should not be regulated!
Of course it shouldn't. But third party services do need to regulated to a certain point where it makes it safe for anyone using one of the regulated exchanges to be safe in storing funds with them (obviously, it's still best to store funds on the trustless bitcoin network anyways).
It should be noted though that these regulations shouldn't be a tool to restrict people from using bitcoin. Instead, it should be actually be keeping people safe by regulating ICOs, exchanges, etc.
There are many advantages which bitcoin offers to people that are currently unbanked, underbanked, or living in a country which a non-working fiat currency. And we are already seeing an emergence of these bitcoin users. These benefits are clear for me, but it does take time for adoption to catch on.
