Wow!
Jay you have said it all, bitcoin has a higher use case compared to gold. Bitcoin can be used for payment, Investment, Store of value, Donations and Smart contract so why would I choose gold over bitcoin. Ha ha if money can't buy your love, maybe bitcoin will do.
Obviously you can, because I have also seen people who propose to their love after owning Bitcoin, either he has sold Bitcoin to build a family by getting married, or he still has it today. Because maybe he has also fallen in love with Bitcoin after knowing more about Bitcoin which can indeed be used as payments, Investments, Store of value, Donations, and Smart contracts. If you have a lot of gold in your life I think you can sell some of it to buy Bitcoin if you already know a lot about Bitcoin. But that's just a small suggestion from me because the final decision is still in your own hands.
If you have a lot of fiat money (Paper money) you should consider buying both Gold and Bitcoin, however personally i would put more investment in Bitcoin as compared to gold. The reason i am saying this is because the gold being less volatile while bitcoin being more volatile but gives more ROI.
If you only have Gold, better sell some gold and buy some bitcoins before its too late. The current prices of bitcoin are good to buy.
Also if you only have bitcoin, then it depends upon you if you want to buy some gold too, I would say to keep your portfolio in bitcoin but later when bitcoin reaches new All time high, convert some of that bitcoin into gold.
