who are really the crypto-investors? how many are they?

to answer these questions, I am launching a study to understand better who they are, what are their motivations and objectives, and how do they invest in crypto-assets.
I would welcome any help, starting with answering this questionnaire : https://www.surveymonkey.com/r/Q2LK8FM
once finalised, I will publish the results of the study, with both quantitative and qualitative data
thanks in advance for any help!
