What services does a crypto marketing agency offer?

I'm curious to know, what kind of services does a crypto marketing agency typically offer? Are they focused on promoting ICOs and blockchain projects? Or do they also help established cryptocurrencies with their branding and outreach efforts? How do they go about generating buzz and interest in the crypto space? And do they have any expertise in navigating the complex regulatory landscape surrounding digital currencies? I'd love to hear more about the services they provide and how they can help drive success for their clients in the world of cryptocurrency.
