Money has a spirit, and that spirit is Increase or Decrease. It can never seat on the fence, once you keep doing what Will Make money grow, it keeps growing, once you stop, it starts reduced instantly, just like the crypto currency chat.
If you keep a million in a warehouse, and didn't touch it for long, this is what will happen, while the currency keeps decrease in value, the value of the money keeps decrease, like while when you keep that same amount of money in an investment firm, once the value of shares increases, the value of the money increases, so don't think money kept for long remains the actual value.
No sitting on the fence when it comes to money especially nowadays that inflation keeps eating away our purchasing power every minute. It sure boils down to either you make it grow or not.
