Agree,we cant blame the advancement  of technology  just because of the rampant spreading of child pornography. Actually  the technology cant be blame because  of how people  abuse  it . Child pornography  are leaded by those persons who are craving for easier money and less hassle they use innocent  children's to be their  tools to earn.I am very sad that because  of technology they  able to operate,why are many dont have conscience and do this sinful things.In other hand they say some uses bitcoin in children pornography.They don't  have  evidence  that  bitcoin is being  used,and I cant also say that they  are right  because   the existence  of abuse is already  present  before bitcoin  was born.If bitcoins  was used to do sinful  things this will be awful  and inconsiderate.
