Hi,
Pardon me for the confusion.
What i meant cheaper is
If bitcoin is cheaper comparatively to gold, then invest in bitcoin.
If Gold is cheaper comparatively to bitcoin, then proceed with gold.
If you stick to the ratio of availability, you can easily predict the reasonable demand and weed out the noises of hype or manipulations in an asset. That way you can set yourself the entry point and exit point based on your risk appetite.
Eventhough 99% odds are with you, that doesn't mean you will win for sure.
Gold & Silver ;; Bitcoin & Ethereum are better pairs. I wont go outside of them. Still choosing an asset for investment out of the four is pretty much subjective based on the risk appetite. Profit & Risks go hand by hand.
Choose your risk and choose your profit.
