I'm not a fan of "vote for better money" because there's nothing to vote for on the ballot. Imagine...

guy sees sign

"hell yeah, I want better money, tell me what to vote on my ballot"

"wait, there's nothing on the ballot for this? you want me to learn a new skill and gain new knowledge? I dunno man, seems like a lot of work or a scam"

Bitcoin and politics have nothing to do with each other, as it should be. I don't think being election adjacent is a good look for Bitcoin. Elections are partisan and people's minds immediately go to "okay, so which side is Bitcoin on?" when Bitcoin doesn't have a side.

Got Inflation? Get Bitcoin is much better because we're all feeling inflation. I think the slogan is a little passive/vague compared to the active, singular action of "vote for better money"

I'd think about building the slogan around a single action that you do with Bitcoin that can help fight inflation on a personal level. Maybe something like Got inflation? Save in Bitcoin. the slogan should lead directly into a thing that the person can do for themselves right away.

Good luck 👍
