Me (and lots of people) have been in this discussion before. The easy tag/strap/pitch then was:

join hive. learn crypto. explore an interest.

The first two are great, especially earn crypto turning into learn crypto. The third, though true and honest, not so sticky.

Taking what you are saying:

join hive. learn crypto. own your data.

or

join hive. learn crypto. censorship free.

the one I'm playing with is:

join hive. learn crypto. create new worlds.

I'm thinking of having that in a circle around a QR code that links to a landing page (yet to be created) on Hive (probably peakd) on a sticker. The landing page is where I guess the pitch will sit with links to other information/resources.

I'm also playing with having different stickers made, all with the first two calls to action, but varying the third one according to the audience I'm with (writers, community groups, gardeners etc), the audience based around my interests and people I come across in my every day life.

So for writers, it might be:

join hive. learn crypto. build an audience.

or

join hive. learn crypto. connect with your readers. - too long for a decal? 😂

For community groups:

join hive. learn crypto. build funds.

I need a designer to help me 😁. Also witty ideas for the third call for different groups - say, gardeners or makers and artists,
