It depends but for a long time investment I will definitely go with gold because it is much more stable than Bitcoin.No investment can guarantee a profit or loss it is only time that tells that.The value of gold in the market hardly fells low unlike bitcoin in which their is no such certainty.Secondly gold prices quickly goes back to normal after fall unlike bitcoin which takes a lot of time to recover from huge fall so with long time investment I will definitely go with gold.
Everyone will have different thoughts when it comes to this, but I'm sure Bitcoin will soon replace Gold at some point because based on what's happening, Bitcoin looks better than Gold.
However, only 1% of the population is aware of the existence of the crypto market so now is not the right time to compare as both have their own strengths.
