I hope you did not forget that Bitcoin has a limited supply and cannot be increased. Bitcoin price will increase with scarcity. While Gold has unlimited supplies, and we don't know how much gold can be mined from the earth. Also, I have heard that some planet is fully gold. If humans can manage to go there and mine Gold (not impossible these days), you never know how much gold will be there. This is not even a debate. Whoever trusts and understands Bitcoin won't compare it with Gold. Whoever doesn't trust Bitcoin, you won't be able to make them understand what you are talking about. They will say it's a scam and gambling.

However, The primary purpose of Bitcoin is not to increase or decrease in price only. Bitcoin is for enhanced privacy and security and gives you to power to control your money. It's your own bank which cannot be stolen, and you can access it anywhere if you have internet. At the same time, Physical gold is just pieces of jewelry and can be stolen in various ways.
