just think of this, when BTC reached almost $20k its 6millions times of the price when it started compare to just a x5 of $20k to reach $100k it just like before most people dont even believe that it can reach $1.
Of course it does not make sense to think this way. Then we cannot even pronounce the value that Bitcoin can achieve in 100 years. Yes, we have made great progress so far. But of course the price of Bitcoin will also have a limit. The 100K target is seen by many as possible. There are even predictions pointing higher.

McAfee famously claimed in 2017 that if Bitcoin doesnt move above $500K within 3 years, he would eat his own genitalia on national television.

I think I now see the posibilty of bitcoin's price increasing to a hundred thousand USD or even more. However, looking at one of the predictions (for 2018) in the image you provided, the prediction failed.
This image includes a lot of predictions. We call this a prediction because there is always a risk to fail. We are seeing Winklevoss prediction has failed. But there are a lot of predictions in there. Look again.
