Banning it will not stop anything actually, it will just force BTC to step into underground pace. The same thing with drugs and stuff, it is illegal in most countries but that dont stop people from using or distributing it. Although this would means that BTC will be acknowledge at something similar of "criminal related stuff" or so
This will be a breeze of air and the best possible case ever but some BTC user despise goverment and also tax. Last I heard Elwar ditched all his credit cards and going to live without paying any tax
P.S : I lost track on this news, perhaps you could use search function for it
To be honest that a fault from the BTC user. Media play a role in reporting a case which unfortunately the case is about someone using BTC to purchase some illegal things i.e silkroad. Its not the media that ruin BTC but it is the BTC user that ruin it, most people will now see BTC as a criminal related stuff due to all this negative publicity
