I disagree tottally with the above assertion that "politicians believe that bitcoin will stop corruption".
As a matter of fact, bitcoin helps politicians to be more corrupt without anyone noticing.
So politicians like bitcoin.
They can launder money with bitcoin untraced.
I don't think it can stop the corruption the question is what's the relation between a cryptocurrencies and Politicians?. Bitcoin is decentralized which is working for their user to increase their profit.Its just a internet currencies and nothing.
