No a bad thing.
If you followed the news you noticed the part that they do not want to be called a crypto. They want to produce something that can be regulated and be used globaly. The regulated part is what distanciates it from the rest of crypto.
In essence goverments wil know how much Libra you hold and what you spend it on. It will be another way for FB to monitor what you do and when you do it.
It might be good for now as people will be looking at crypto and buying in some thinking they can buy it with BC later. And they probably will be able to. But after the initial launch it will be bad if you think about it logicaly.
