If you operate a Bitcoin exchange you need to know my customers. Running a digital currency exchange in the USA is begging to go to prison even if you try to follow the law. You need to figure out how much tax you owe, etc. If you make a new drug it needs to be approved by the FDA. There are regulations and laws galore, you are naive as hell if you think drugs being illegal to sell is the only way that the government strangles businesses.
