It can lead actually since it is full anonymous
Yes, it will be much more convenient due to anonymity. Bitcoin will bring corruption to a new level
I say Bitcoin only has partial anonymity it does not have that feature like other alts do and if you chose to bribe someone using bitcoin it would be easy for somebody to link a transaction to you which is evidence on its own, so using bitcoin for corrupt practices might be a bad idea because bitcoin is an open book. Am confident that bitcoin can not lead to corruption
