If i am just a new investor in bitcoin having a price of 100,000$, i think i will only buy a small slice of it because i could not really afford to buy a whole of it. I am going to hold it, let it grow up higher and if the price is already right for me, then i will sell it right then.
I think not many people have a bitcoin when its price is $ 100,000. At that time only rich people could afford to buy bitcoin, so hardly imagine bitcoin going to have such a day. I am not confident I will buy more bitcoin at that price (even a small slice of it) and wait for higher price.
When the time comes that bitcoins reach $100k then there is no people who are going to invest a huge amount and they will wait for the price to dump before investing again unless they are not well knowledgeable and they will do some drastic decisions that they will regret in the future.
