That gold chart is made over a 40 years period while bitcoin chart is made for the last 2 years. You just can't compare to charts like this and base on them to make a prediction for the future. During 40 years a lot of things can happen that could seriously influence the price of an assets, especially if we are talking about gold because the economy changes,the supply is changing,the politics are changing and many other factors while all of this don't change that much over 2 years. Besides that bitcoin and gold have different factors that determine their price movement overtime.
I do agree that those charts are not comparable as both have different foundations.
Gold chart has been established so many decades of trading that the foundation is already stable and strong.
Whereas, bitcoin chart is considerably weak and at any moment in time will change course.
The price change of gold is predictable while btc price can greatly change over the next few hours.
The trend might be similar but the meaning of those charts are totally different.
