I don't understand people who post and then don't even look at what they posted...
For years, various analyses have talked about 2% of the population owning BTC, so it doesn't really matter whether it's 2% or 3% because in any case, that number is too small considering that 15 years have passed since BTC was created. In addition, as someone already mentioned, only those who keep BTC in non-custodial storage can be considered the real owners, and others who use CEXs as wallets are not in a position to say that they own anything.
As things stand now, it seems to me that it will take a very long time for the number of ordinary people who own BTC to increase, because for the average person who looks at things superficially, the price of 1 BTC of $100k+ is a demotivating factor - while for those with deep pockets, it is not too important.
