What if all those big corporates and businesses starts using crypto as a mode of payment just to avoid tax which will cause a direct loss to the government which uses tax for the betterment of the country. This might not affect corrupt countries as it doesn't matter because tax money goes to politician's coffers but what about developed nations?
In my opinion, it will have a rather bad effect on the economy in general, not in particular with corrupt countries. Because humans are not controlled by the law, we will turn into a more evil and more ambitious person. then people will no longer use fiat money, they will directly use crypto to manipulate like the whales did and will make the decentralized market spark. That is also the consequence that governments around the world do not want, so they have to make quite a lot of laws for crypto.
I do not agree with this statement, people are worried about governments and their inability to get enough funding if cryptocurrencies take off, but we are living in a strange age, governments are bigger than ever and they want to be even bigger, but during most of history governments were small and cryptocurrencies will allow us to get back to those days, the economy will become more efficient as we need to pay less taxes to a smaller government, a big government is a hindrance to the economy and not a boost.
