It gonna be a tough call because we have Japan, Australia and to an extent South Korea which are pro bitcoin and cryptocurrency and on the other side, France, Germany, Indonesia and China who opposes bitcoin, and then neutrals like  India and other nations as well.

Let's wait and see, I don't think that this is a priority discussions, there are pressing issues need to tackle and if ever they determined that bitcoin regulation is needed, there will be opposition for sure. In my view, those against crypto will have a hard time selling their aim in this G20 summit. No final formal actions would come out regarding a joint bitcoin regulation amongst the member. Each nation has its own governing body to decide whether to regulate bitcoin or not.
