Some of those big wallets are held by the likes of Grayscale or now various ETF’s. So, at least by extension, the number of 1 BTC holders might well be a bit larger than the one million addresses might suggest.
And it only takes a 15x from here for all of those people to be millionaires. 😎
But, just think about the hype that can get created when people want the bragging rights, where the rich and famous are looking to tap into Bitcoin, for the same reasons they will buy a Lamborghini. Rather than walking around with a Tiffany's diamond necklace, they have a platinum hard wallet hanging around their throat instead.
At least a few of those people will get killed for being that stupid.
Not your keys, not your crypto? ;D
I said, "don't underestimate the power of ego" - but also, don't underestimate the power of human stupidity and greed!
