I’ve just read the whole thing. Researchers did an excellent job in understanding Bitcoin to survey this understanding in the population. Remember that voluntary surveys like this are non-probabilistic. Here is imo an underrated quote:
Bitcoin owners were more likely to have low financial literacy (38 percent), compared with the overall population (27 percent) (Table 3). […] This yields an interesting result, as those with high financial literacy are more likely to have heard of Bitcoin but less likely to adopt it.
I think this is consistent with what Andreas was saying: people who have easy access to banking do not need Bitcoin, as they are already privileged. Others, like immigrants who send money to their families abroad, are much more likely to hold Bitcoin because they have a direct need for it.
