It is easy to take historic prices and to extrapolate certain fixed trends, based on that... but it is a whole other story ...when it comes to reality.
Who would have predicted the 80% drop in the Bitcoin price since 2017? If you used historic data back then, then we would have seen a $1 000 000 bitcoin price now.
There are just too many things that can go wrong, for people to base their future predictions on historic data like that. Gold is more predictable, because the supply is limited and it is more stable. (also, because the price of Gold is being manipulated)
