- Around 30,000-60,000 people with more than $1 million worth of bitcoins
Really? How do you determine this? Is it assuming one address = one person?
I don't buy it either, this number is way too high, if it was true, this forum would be full of Bitcoin millionaires. Most likely they just used the logic that 1 address = 1 person, and then took addresses with more than $1mil, but it's obviously deeply flawed, as one person can and usually does own multiple addresses. And then there are exchanges which hold enormous amounts of coins, and many of them are in cold storage so it's even harder to determine how many coins people own.
If we consider smaller amounts like less than 0.05 than there would be lacks of addresses holding that amount of bitcoin. What OP did is perhaps just counted addresses having larger amount of bitcoins considering those are active holders but there also are other people who like to prefer holding smaller amounts onto their exchanges and leave rest of the amount in hardware or cold storage which would never be possible for us to count because already there are a number of hardware wallets and cold storage which people use to safely store their coins without the thread of getting hacked or lost.
There already are a number of bitcoins mined and only classifying people with maximum number of bitcoins would not be good as the statistics should be comprehensive.
