It does no matter for good cause or bad cause because what matter is bitcoin are not made for bad cause, if thare some peoples who use bitcoin for bad cause then it is not the blame for bitcoin, just like peoples who make and sell knife where knife can be used in the kitchen or can be used to hurt peoples.
I'm now using bitcoin to gather funds to advance the movement I'm on.
Bitcoin is as easy to use to found something secret as it is with any other currencies for the people who really want to make something anonim.
