100k is just a round number without any significance especially and the important thing to note about any Dollar price is its a constantly changing value. Dollar has no fixed exchangeable value, the only reason dollar so far has not visibly varied to any great extent is other FIAT standards made a deliberate attempt to track in line with any inflation or dilution of the dollar standard. Real prices relate to real goods and dollar has lost alot of value in just last 20 year obviously previously too, in future 100k will occur because BTC does not dilute its users in this way and any new supply is known from the day BTC first came to be.
