cool, but what meaning of the model? it is impossible to predict the price
As stated on the website:
Mission Impossible: Modeling a market price. This is a Simple Linear Model - Alpha Version - For Education Purposes Only
It's not very likely you'll make an accurate price prediction using this tool, but there's no harm in trying.
The purpose is rather to give you an idea what the price could be (not will be) if some criteria are met (ie if BTC takes over x% of gold market etc).
