See both gold and bitcoin have their own pros and cons.
You can invest in gold as it is safer but less dynamic option.
BUT you can not purchase things directly by just offering gold to someone.
On the other hand bitcoin is a currency , a versatile currency.
It can help you with purchasing things.
Yes bitcoin is good as a currency and can give you quick profits whereas gold is more stable and can be profitable in long run, investing in both of them can be a good decision.
