All the signs that Bitcoin is going the Silver way. It was declared that Silver will be precious metal and it will be traded on buying and selling and also speculations/predicting events because silver has many uses in Industries, electronics (TVs, computers etc..), a cruise missile has 16 kgs silver that is the reason major war takes Silver price to new highs.
Now Bitcoin has been declared as a speculative asset by governments (deal at your own risk).
I don't think that you need to compare the silver to bitcoin because as far as I know bitcoin is greater than the silver.
