I think no. The presence of bitcoin is not intended to reduce corruption, for corruptors who know bitcoin then this is a good opportunity or place to hide their money so that no one can track.
but its a good sign if all the bigtime names put there money into bitcoin all the bitcoin investor will benifit because of the price up but the blockchain technology has the power to reduce the corruption in our goverment ..
I personally don't believe bitcoin reduces corruption, at least until now. It needs better conditions to remove corruiption from the world.
