Just filled survey. It might be difficult to get 1000 responses, it's quite big number, but I hope you'll reach it. I think this survey is very well made. Often when I fill surveys, I find that questions in these surveys is strange, or bad constructed. I also just don't find answer option which is suitable for me. This isn't case with your survey.
Just one little suggestion : in question about wallets, you should write Blockchain.com. Because Blockchain isn't same thing as Blockchain.com.
