Hi I will split my answer in half, a few tips and guidelines you should consider if you decided to do it yourself and on the other hand if you will decided to hire an agency

Crypto marketing is different from other marketing in many ways but the most notable is that it's still new and ever-changing, what works tomorrow might not work today.

This is an entirely different kind of work, here are my tips:

1-Learn about the technology: if you don't understand how it works, you can't sell it, it is not enough to be able to explain it to tech-savvy and crypto traders, it needs to be easy and simple to understand for newbies.

2-Dont spam: crypto communities are very unforgiving when it comes to this, if you spam you will be banned and blacklisted very quickly.

3-Where to publish? channels like Reddit and crypto forums, are more important and can be a lot more relevant to your project than Facebook or Twitter.

4-The content needs to be high quality and interesting, the level needs to be like this Guerrillabuzz Blockchain Marketing just a rehashing of the same old stuff, the idea is to educate and inform potential investors, not to sell them.

If you will decided to hire an agency:

1-Do your research: not all agencies are created equal, some might be better at paid ads while others excel at community management, find one that fits your needs.

2-Check their references: ask for other clients they have worked with in the past and see if they were happy with the results.

3-Experience: it is important that the agency you hire has experience working in the crypto space, they need to understand the technology and the communities, and show solid study cases that they know what they are doing.

4-Team and content: make sure you like the team and that the content they produce is high quality, check out their blog or website to see if their style is a good fit for your project.
