I still think 0.01 BTC payment to join this forum would help the most.
It is very difficult to get 0.01 nowadays, even when its value is just $6. It takes absolutely ages from faucets, impossible to mine from cpu, months from first gen asics, or may be a 50 mile drive to a bitcoin shop or atm.
Fiat > BTC, of course. Increase demand for BTC. To allow free entrance here works directly against demand increase and on top of it all we have scam
shits going around
every day! Cost to attempt scamming? Almost zero. What to do with scammed coins? Most likely sell for fiat, putting preasure
on major coins, those one can convert to fiat. So in the end very little good comes from free access to this forum. The number of damaging posts from
newbies exceeds number of beneficial posts by massive percentage.
Newbies are allowed to post links to supposedly cryptocoin GUI clients (Qt) and other executables and suspicious stuff like infecting people computers
is no big deal for Bitcoin. It is so because we need more "Bitcoins scammed!" articles in media, right?
Liberal mindset was appropriate around here but it is no more, at least not when it comes to forum moderation ... it will backfire badly sooner or later
and then bullshits like "Use your brain!" will become just echoes of failed management.
