I keep lists on Twitter, and now have almost 200 "Crypto-Influencers" on this list:

Right now we are very incestuous on Twitter. Most STEEMers have only other STEEMers as connections. Therefore, no one else sees the tweets.

A good strategy is to follow 1-2 crypto tweeps each day and get them on a list. RT from the list a few times a week. RT with a comment for better results. Try to engage those other crypto people, and over time they will be following you.
