Bitcoin make the corruption and related activities much easier than the transaction we make through fiat or other fiat system. Even now a major collapse is made by a team sending ransomware and demanding in terms of bitcoin to be on the secure side. Already they have collected 33000$ worth of bitcoin.
In my opinion I think whatever our means of exchange, curruption lies in the very soul of people not the medium of exchange. Fiat or cryptocurrencies, curruption will continue if the people is greedy, don't blame cryptocurrencies in illegal transactions, it is the people who use it are at fault. We don't blame the fire burning up homes, we find the fault of the origin of fire.
Corruption in this dispensation has turn to cultural believe in almost all climes of the society but the degree or intensity differs across board. With bitcoin coning into the picture, then I see people exploiting it to meet their selfish ends and carry out what already is in them. In other words, bitcoin won't lead to corruption but increase it by those who are already in it.
That's right, the unending desires and the sickness that is ongoing through generations has been infecting everything new. No matter what is the revolutionized way of things if the chain of curruption won't be stop then still everything will be currupted. The problem is not about banks, governments, cryptocurrencies, capitalism, socialism, democratisation ------- but the problem is on our selves. Ourselves
