The bitcoin is a currency like other fiat currencies in other parts of the world.So, how can any one claim that only bitcoin is spreading child sexual abuse fiat is also equally responsible for it,even the people who use any kind of method to transfer money for such illegal work are responsible and they must get punishment for that as well as society have to stop blaming bitcoin and search for such people who do this type of activity and take initiative to stop child abuse rather than making affords to drop the market value of bitcoin.
