I think regulation will be a part of mass adoption. There's no other way around it. And when regulation does happen, it will probably make prices plunge.
There will always be unregulated crypto because they just can't regulate 100% of the industry. If you and I could make our own blockchain, then there is no way they can regulate everything. Most of the coins are decentralized, and even Bitcoin has people wondering who the founder is. When there is no one to take responsibility for a currency then there almost nothing they can do.
