I noticed duplicate copy in the subheading:
"How do we get buy-in from the rest of the team?
-So you're building something new and you're wondering if you're building the right thing?-"
(https://bitcoinresearch.xyz/buy-in-from-the-rest-of-the-team)
This subheading duplicated from "Are we building the right thing?"

I wrote this to replace the duplicated copy:
"How do we get buy-in from the rest of the team?
You need to share compelling evidence from your research insights with your team."
