What percentage of Bitcoin users do you think use the forum actively, or have at least registered?
Few thousands out of few millions, so about 0.1%
From this view your pool options are ridiculous.
What else do you think is worth considering before submitting your answer?
Multiaccounting is norm here, so sign up numbers does not represent number of unique users here.
I think all unique users are into bitcoin and there are just a few who are just here to advertise there own ICO. I would just call this multi accounts as unique users but even though everyday there are newbies who really are newbies, i doubt they would be into it in just a month. People got to wait for long term at least to be termed as bitcoin user that is used for trading and that they are manipulating there btc in there own accord.
