You're absolutely right but there are a lot of Bitcoin millionaires (mostly early adpoters) who can still donate 10BTC to the forum but it rare though for them to do the donation. Wait a minute, the donation is even enough to participate and pay a maintenance cost in the
build a seastead which was once introduced by Theymos.
I do not think that there are a lot of Bitcoin Millionairs.
I would bet that there are less than 5 if any other than Satoshi (and even his amount of bitcoin are not sure that these expected 1 million belongs to him)
Not counting an exchange as these funds are only in custody to their customers (but sure not your keys, not your coins)
They are talking about millions worth of BTC in USD not millions of bitcoins. There are quite a bit more than 5 out there. According to
there are more than 93 thousand out there holding more than a million dollars worth of BTC. It wouldn't be surprising if many of these folks were members here at one point and maybe there's even a few lurking around or participating here and there.
