The mere fact that btc deals with huge amounts of money means that it's impossible to think it won't be prone to corruption. It's everywhere even with small communities. The very definition of corruption applies to bitcoin if you think about it. Hopefully it just doesn't bloe out of proportion that will lead to btc's ruin
Bitcoin itself can be used for a variety of purposes. Someone uses it for good, and someone for illegal activities
It depends on the various personality of every person. If the background of the users is really bad and it has a high chance to be used as an illegal activities. But compared with the fiat currency and fiat still become a leader to be used for the illegal activities especially for the money laundering or corruption.
And there are people who says they won't use bitcoin because it is illegal but if they just think about it and widen that narrow minds of them, the most used currency for illegal activities is USD/fiat . There is something wrong in the question of this thread it should be can bitcoin be used for corruption? not it can lead to . It is impossible that bitcoin can lead to corruption, It's in the person's personality tho bitcoin and other currency can be a tool for it .
Many people is mentioning BTC as illegal not because of their narrow minds, but for fear and half knowledge about it. Many countries have mentioned using it illegal but no rules are their still, and USD/fiat is used more for illegal activities because its a world currency and BTC is yet not been common for the casual peoples. But yes definitely I agree, Bitcoin can not lead to corruption, its the use of Bitcoin which can lead to corruption.
