We want to see how high Bitcoin can reach for the last decade but let's just give an example of how much Bitcoin was a decade ago, so 2015 started the year with $200-$300 price and now look how much it is just in a decade.
Considering 2015 for speculating about 2035 makes sense but the price level seems misleading to me; otherwise I guess you need to consider the ATH by 2015. Because, bitcoin is known for dumping up to ~80% in a bearish year which means we may get into a complete different price range if we consider the prices at random dates.
