According to the details from the meeting, the G-20 presidents’ group received collaborative support from the International Monetary Fund and the US. Speaking to Reuters, Yellen mentioned that there won’t be an outright ban but rather a strong regulatory framework.
This is why we end up with such a thing and we will have that framework in order to make it even more legal. This isn't a bad thing, it's in fact a good thing because it means everyone will know what to do with it. Knowing what is legal and what is illegal is a great benefit to investors, you will have absolutely no fear left about what you are doing.
Harsh words! But don't forget for how long many governments chose to ignore Bitcoin while a lot of people suspected that this could one day going to be huge. By the time governments also came to the conclusion, the industry has already grown so much that governments didn't even know where to start with their regulation. Now I think that Bitcoin eventually benefited a lot from being ignored. The same counts for Ethereum as their ICO would have been labeled a security offering and would not have taken place. Once it grew into this massive network they couldn't stop it anyway anymore or sue someone. Now we are at a point where they did indeed realize that a ban can't be enforced.
