Greetings
How are you doing?
The development of technology is offering option to move away from the cash system to the electronic wallet and digital cash.
In Ecash the solution to secure your payment with lightning on the bitcoin network second layer provide so security against the scam and the pull rug problems.
It may seem too complicate for the people who like to spend cash for their daily activities at the store or in a gas station.
I would recommend using a small amount of cash when you recharge your account to be sure that you understand the mechanic involve in this process of payment that just came in our life.
There are a lot to learn about privacy and fund security when it comes to manipulation of E cash system.

The cost of living will not slow down, so the money we hold in our hand as fiat is as well losing value over time.
Conversion of fiat to rare earth resources is cool for people who are enough to survive on the daily basis without selling the gold or silver they hold somewhere in a safe.
If you do not hold enough money and need to spend what you have earned as soon as the necessity occurs, you may move part of your fiat wage in Bitcoin.
Then you shop with your grocery store, who accept bitcoin to win on your trade each time BTC move up in value. It is a constant growth in value but also drop but in the long run up.
