I have the feeling that many bitcoiners try to spread attention and participation way to enthusiastic.
You should instead make a similar approach as any Business Developer in Companies, when it's about winning new business.
A, now outdated but still effective and easy to learn approach is, split your attempt in four chapters:
1. Attention:
Most important part, here the decision will be made if the (potentially) customer even reads through the rest of you message.
This part should show some simple solutions to his problems and
not be techy.
The only target here is, that the customer get's the impression, that you have really something interesting to offer. It's not even necessary that he knows what after this section.
2. Interest:
Here it's all about to get his interest. If you will communicate more than one time with him than after this chapter you stop. It's about getting him thinking and inform himself. It's planting the spark
If it's a one time approach it's the time to show some fitting example solutions.
3. Desire:
Now you show them why this is exactly what they need. If you gotten to here it's time to get into detail, if you where successful in the points before no one will stop reading here. Convince them that BTC is
the solution to their needs.
4. Action:
Now, and not sooner you present them your offer ( hard if you are offering something for free!) This is the point when you try to let them take action, maybe point them towards services that help by the implementation.

I think a good template when we approach businesses would be really helpful.
