So, in short, they are still allowed to trade with it and use it, as long as they are 'okay' with the 'risk'. It's only financial institutions that can't work with Bitcoin anymore? Is this right?
Yes. I read the full text and it said that websites are people can have and trade bitoins at their own risk. Financial institutions cannot join this market due to the non-currency property.
I doubt any financial institutions were using it to begin with so this is a non issue for the moment.
