Buying gold is very easy. But the problem is when it comes to selling.
I disagree, buying gold is not as easy as you have thought about it, this is a centralized physical asset we are considering and there is a need for you to understand that you will have to go through a centralized means by fulfilling kyc terms before you can get one, selling it as well may demanding before you can get a particular buyer at your selling rate.
The process of selling gold appears to be much more complicated.
This is true, compared to bitcoin which is more easier to sell or buy using p2p
