This is a very difficult question to answer given that there are lots of members who are active in this forum who have a diversified portfolio.

Just to give you an example, I am an active user in this forum but my total accumulation of BTC since 2017 from participating in campaign signatures is around ~0.6 BTC in total. On the other hand, there are other users who are active in this forum but they have more than 1 BTC on their wallet due to various reasons (e.g. campaign signatures, services, investments, etc.).

At the end of the day, this question is just too difficult to answer given that there are too many factors to consider. But it is safe to say that at least majority of the active members in this forum have BTC on their wallet currently.
