Some general suggestions:

1.  If I was an editor that received unsolicited email asking me to write about something, if I take the time to read it at all, it better give me a good reason to write about it.  This does not.  Much like cover letters to resumes, you are wasting your time unless you tailor your message to the exact person that's going to read it. 

If you're sending this to The Economist (or similar magazine, just putting one out everyone would know), you would pitch this as a potential article about the difficulties of developing a legitimate alternate payment ecosystem within an industry dominated by get-rich-quick schemes and  immature, rigged market that makes trading penny stocks look safe.  The crux is you still have to define what really makes UTC standout, what is the compelling story that makes UTC different than other coins in the alt market?  What struggles have you overcome?  What developments set you apart that make you not like the other coins that exist in the rigged market?

If you were sending this to Wired, you would pitch it as a piece about the rise of ASICS and altcoins, and the struggle to keep video card mining as a legitimate means for cryptocurrency to not become the centralized beast it was meant to oppose.  Emphasis on hashing algorithms, ASICS vs GPUs, and, once again, a compelling reason why the story should revolve around  how UTC fits in this picture and why it's different. 

So on and so forth.

Do not send out letters with generic platitudes about great people doing great things and then list none of those things or people.  Do not spam links that require an interested party to try to figure out why they should be interested.  No one of any importance is going to take any of that seriously. 

And most of all -- if you don't have a compelling story yet, do something so that you do have one.  You are not Coke, you can't just spam your name as part of your advertising campaign.  You don't have any brand recognition. 

Notice the links above about DCGirl were all about her and her relationship with crypto / UTC.  Get the interest?  Women and Crypto / Coding are about as rare as Gaming and Women.  It's unique, hence, something worth writing / reading about. 

And that should be your ultimate litmus test for anything you send out -- Would you want to read that email if it showed up in your Inbox?  Would you care about what that person said if you didn't know them or anything about what they were talking about?  Would you click on any of those links?  Would you want to know more about it at all?
