Crazy to consider that the amount of bitcoin holders in the world is still so low.

This might be a bit rambling, but I was thinking about this a lot very recently and i'm not sure what to make of it. Grateful for any insights you can share...The global population is over 7 billion people.The minted supply of BTC is around/above 18 million.It is estimated that at least a couple of million BTC are lost forever.A small amount of individual holders possess vastly large BTC balances. (aka whales)Most BTC hasn't moved on chain for over a year and is presumably "not for sale".​This is the part that baffles me though:There are over 45 million "millionaires" world wide.At past and current trading prices, buying just 1 BTC would be a minuscule purchase to this class of wealthy people.Not to mention the many people world wide who aren't millionaires, but who could also easily afford 1 BTC at past and current trading prices.​Here we are 10 years after bitcoins launch and it seems as though everyone knows the word "bitcoin" even if they don't understand what it actually is or how it works.I just find it so surprising that amongst the vast population of humans on earth, so few humans possess any amount of BTC at all, at this point in time.​Given the fascinating speculative "number go up" phenomena of BTC we have witnessed in past growth cycles/bull runs, how is it possible that the global population of wealthy people still have no/little interest in participating in BTC at this stage of the game?The ticket to get on the roller coaster is relatively cheap (and divisible to any amount they choose to acquire as per their risk appetite). But again, even at all current and past trading prices, 1 BTC would be cheap for them.How are there not more holder in the world?​Ive rambled too much lol.
