Yes it can, because all the transactions of bitcoin are anonymous and the corrupt people needs such type of platform to save their black money and to transfer them anywhere without taxes and without government consideration. Everything can be use either in positive of negative way, this is the negative use of bitcoin to do corruption.
Correct, But we do nothing about it because bitcoin is an open source to anyone. Only the bad things is there are bad people out there who are greed and once they found out this bitcoin, for sure they will take advantage of it to use it for evil things or illegal activities.
