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.
Yeah bitcoin has anonymous and decentralized facilities and that's what criminals or criminals use to do illegal activities.
The corrupt just need to wash their money into bitcoin and then they can convert it again to fiat without being seen. That's bitcoin expertise
There are ways to track it though but with the use of mixing services it sure does help criminal activity a lot.
I have yet to hear of bitcoin being used in corrupt cases though, but I guess it's only a matter of time now.
I think the mixers have more benefits to other people and yes with mixer they can hide their money but still I will say that with it corruption is not possible because all of the transactions are appear on the explorer and I think the mixer owner will know about the transactions. So corruption with bitcoin is not possible.
