Bitcoin in 5 years

Say Bitcoin goes to 100k or 1M in next few years. My concern is in 5 years, everyone who doesn't have Bitcoin will have bought by then and the rest of people will never buy it. Will we ever run out of people who are new to buying Bitcoin? If in case we do what would be impact on the price? What would be the impact on Bitcoin future?

Edit: In 2010 the reason for someone not being in Bitcoin was they hadn’t discovered it yet. Say now or 2027, the reason for someone not being in Bitcoin is that they know how it works but decided to not get in.

The number of people that were discovering Bitcoin and deciding to get in is approaching zero. Say by 2030 everyone will have discovered about Bitcoin and would have made the decision to get in or not. Zero people will be unaware of it, there is possibility of no new buyers coming in.

Edit 2: The question is most people have been unaware of Bitcoin until recently. Consider this scenario; 100 new people will discover about Bitcoin today, maybe 20% decide to get in and 80% don't. As Bitcoin is becomes more popular lesser and lesser people are unaware who are discovering about Bitcoin and say 20% of whom are getting in. The rise in popularity means at some point, everyone is aware of Bitcoin and has made a decision to get in or stay out. The possible lack of new buyers has nothing to do with the price. It's the fact that at some point, all believers will be in, and only non-believers will be left who won't get in.
