Gold is going up at the rate of 2.5% per month

This is just a rough estimate, but there are 4 data points: 9/6/23 at $1917, 10/27/23 at $2006, 11/29/23 at $2047, and now 4/3/24 at $2296.  If this keeps going up, by 12/31/2024 it will be at about $2800.  That is 30% plus per year growth.  

Maybe I am cherry picking my data, but you could go back another year until late 2022 when it was below $1700 and find another point of intersection.  So the price has broken through this on the upside.  Let's see what the next valley is and recalculate.
