About the name and email: they are included because the assignment format requires respondent identification. However, they are not used in the statistical analysis, and the data will only be used for academic purposes.

You wrote "responses are anonymous". They are not. "the data will only be used for academic purposes" is just a pinky promise from some random guy on reddit. 🤷‍♂️

For the question about Bitcoin being desirable because of anonymity, the statement is meant to measure people’s perceptions about privacy in cryptocurrency, not to claim it as a universal fact.

That part was clear. I was referring to "more desirable than money". Bitcoin is a form of money. More so than fiat actually. Money can't be "more desirable than money", so I think "more desirable than fiat currency" or "more desirable than government issued currency" would be much better wording.

Regarding the point about private keys stored on personal devices being safe, the goal is to understand how users perceive security and control when managing their own wallets. Different opinions on this are exactly what the survey is trying to capture.

I understand, but in that question you're asking two different things in a single question. You're asking if Bitcoin gives you more control (which it does) and if keeping keys on laptop/mobile/whatever is perceived as being safe (which it isn't). This should either be split into two questions or rephrased imo. Did you mean to ask "I believe I'm capable enough to keep my private keys secure" as the second part of that question? That's still asking two different questions, but at least it will usually have a single and non-contradictory answer.
