Since you are just asking for one important question from members, this will be made easier if you can provide a list of questions that you already prepared. We don't want to repeat what's already in there and we could think of other questions.

As for me, Would you rather hold $1000 in your bank account for five years with little interest or would you buy BTC if there's a chance that it could become $10,000 in five years?

"Would you rather to trust your money on Bank that someone can control it or be your own Bank with Bitcoin and no one can control it except you?"

I think a newcomer need such questions about the difference between Bitcoin and Bank to make they understand about the basic purpose of Bitcoin. Most of people might interested with Bitcoin due to money or investment, but that's not really correct way to introduce Bitcoin to them.

Let's say that the participant at the very least ever heard Bitcoin. If you want to know the awareness about the usage and functionality of Bitcoin I think you can ask something like "Do you see Bitcoin as a currency or an investment". I think that question is the basic thing and it made you know how the participant perceives Bitcoin in the first place, therefore you can grow the question based on that.

Also, What I'd like to know the most is, assuming the participants has ever use Bitcoin, how their point of view in term of ease of usage or user experience when they do something with Bitcoin.

1. Have you ever heard about Bitcoin?

2. If yes, when and where?
The where can be a list of sources such as
- Media (TV, radio, Newspaper, social media)
- Someone (Maybe a friend or relative)
- Pyramid schemes hiding behind bitcoin to make adverts etc

3. Do you think Bitcoin is a good innovation or What excites/annoys you about Bitcoin

I hope the questionnaire is related to financial matters such as knowing inflation levels, the effects of printing money, the reason for currency depreciation instead of Bitcoin price models, invest $100 and you will be rich and so on.
Beginners have weak hands, they will not hold cryptocurrencies for long periods and will start selling as soon as the price drops, thus making more losses.

Measuring the extent to which people are aware of Bitcoin is a very good idea, because if you have given the stimulus first to those you want to ask questions.

Why? To be honest, the internet world and the Bitcoin part in it will be very difficult to understand for people who usually work on plantations, factory workers, traders and also freelancers. How can you be sure that the survey will reach your target? then what is your initial hypothesis for now before the launch of the survey?

Before conducting a survey, you may already know much more about what procedures should be used as a reference for those who are still new to understanding the concept of Bitcoin as a whole.
There are various alternatives in conducting surveys, one of which is by applying the stimulus first, as I have stated above.

Because it would be a waste of time, if you spend time doing a survey, but at the end of the conclusion there is no value or learning to take. Then if you want to take a survey sample to several people closest to you, use random sampling, or there are various options:
1. Snowball Sampling
2. Purposive Sampling
3. Quota Sampling
4. Accidental Sampling
5. Systematic Sampling
6. Saturated Sampling Technique

Since is on a beginner level the first question should be; have you heard about bitcoin, how and when? what is your take on the subject Bitcoin? Do you want to invest in it or you are already an investor.

If the answer to "did you hear about bitcoin" is yes, I would add a question like "What you think, is bitcoin dirty/drug/illegal money, or is it clean/as good as any (USD)"?
I mean that you could also see if the old "bitcoin is bad" narrative is still catching...

I was also having something similar in my mind and one of the purpose of this survey is to know still people believe in such bullshit and living away from reality and will guide them towards reality of bitcoin.

The only way you'd be able to properly achieve the bolded parts is with the use of a dynamic ^[automated] survey, as opposed to a survey that comes with a single set of questions.
^{- In addition to those, you have to find a way "within the survey" to provide appropriate sources for your respondents [easier said than done].}
