Money has already evolved several times in human history and will continue to evolve in the future. We started from animal skins to beads and feathers to precious metals and gems to paper and cards. And obviously the next phase has already begun from the creation of bitcoin. This is unstoppable.
Money is very important for us to ensure material and spiritual life. Today's society thrives on and thrives in harmony all even destroying human morality. Through each stage, different value for money. Money in Vietnam is depreciating.
