In my experience, it is not easy to earn 1 bitcoin so I think most of them are investors.
it depends on the persons use of bitcoin, for example:
If people want to use bitcoin as a currency to make payments for goods and services these people will not be worried about owning 1 bitcoin, but people who are focused on Hold are very concerned about having too many bitcoins to hold for a long time.
How does it affect bitcoin?
I constantly wonder if everyone in the world buys 1 bitcoin and hold for many years what would the market be like? is that a good idea? or the best option is to actually start using bitcoin to buy goods and services?
