Yes, it may be that the price of Bitcoin may increase many times over due to low supply but I think Bitcoin may not have a value 100 or 200 years from now it may be replaced by someone else but Gold will be used as a valuable asset.
Maybe humanity won't exist in 100-200 years from now (due to WW3 nukes). In that case, yeah, BTC won't be used by anyone to have any kind of value. 
But gold won't be used either, soooo...
