I have only one answer for present moment - we need no regulation now. Because market is small, and bitcoin using not a lot of people. It must be regulated only by crypto community.
The regulation serves to bring every investor who still has doubts, I am sure many investors are already looking for bitcoin but he is still waiting for a regulation. The brain of an investor is not fixed on this day, but they will guess what will happen and what must happen in the future. Having a prediction is important, so that you believe in the future of bitcoin, don't just focus on today.
