It is believed that cash helps people budget, as using it means you literally can count the pennies. Paying with a card or crypto currency make spending easy and convenient that sometimes one tends to overspend. Sometimes one might not even know the balance of his account but with cash you are always aware of how much you have.
I agree with this statement. Holding cash helps me to consider that how much I have spent and also how much the balance. It prevents me from overspending
This is when you are thinking as person into cryptocurrency, many people outside crypto ecosystem doesn't think like that, they spend how they want, how they feel and how their mood swings but some people who use to plan don't over do it, they used to planned their lives and know what to spend at a particular time.
There are some people who are also not into crypto holdings but spend wisely and don't over do things with fiat. I think been in investment help us to plan very well and reduce how we spend this fiat.
