How many people would you say that own 21 BTC approximately nowadays? What % you are at if you own 21 BTC?

I know it's hard to guesstimate since we can't know how many people how X addresses, but maybe there is some way to make a reasonable stimulation.

I ask this because a lot of people have this dream of owning 21 BTC as a storage of value for the very long term (10+ years). I think it's excellent advice, to own this amount on the most important network ever. I also dream to reach that amount before it's too late, so im hoping the price stays where it's at before we break ATH again.
