I was in the same spot, wondering where to put my money. After looking into it, I decided on gold. It's been around forever and feels more stable. Gold is something you can actually hold, which feels safer than the digital world of BTC. Plus, gold's price doesn't jump around as much as cryptocurrency does, so it feels like a steadier choice for my money.
If you are not for the volatility, gold should be your choice. But if you are up with volatility and you like more the Bitcoin market and its instability in terms of value, you'd even like it more as the year passes by.
You'll see the gains difference are totally way far from each other. As the stability of gold is there and it has become the global reserve standard of most countries, you'll not have problem with its liquidity but tangible wise, Bitcoin is easier to keep. You don't need a safe for you to keep it and no one will know that you're holding Bitcoin.
Well, as for investing we always say about to each their own. We are in a Bitcoin forum and majority of the investors here are Bitcoin holders. But if you're holding gold and you want to invest to Bitcoin too, no one's going to stop you with that.
