Regulations actually weeds out fraud and financial criminal activities in the market making investors comfortable in their investments and not worry that one day someone will make off with their hard earned cash. Now, i just hope that this regulation will be pro crypto currency holders and not anti crypto currency.
That is always the main essence of regulation actually, as that would help put some policies and rules in place that will not only curb fraudulent activities, but will also curb any unlawful doings, most especially when it comes to market manipulations.
I believe the existence of regulation in the cryptocurrency space will really help a lot with that, and I believe as time goes on, with such in place, the market will grow to become more matured, usable, and give investors assurance that the market is somewhat covered from illegal activities to some huge extent.
