I do not think that there is a need to associate regulation with the negative impact!! In fact, regulation sometimes prove to be beneficial for the country because everything moves in a systematic and organized manner. So the environment of the crypto market, remains friendly for the community because there would be lesser scams and frauds. This way there would also be a controlling authority to look over the market conditions and regulate the acts of the market. Yes, we do need regulation unless it curbs the activity of the market in a negative manner.
