Fiat or physical money is literally dirty since the day Jesus expelled all the merchants and money changers from the Temple to today's Coronavirus pandemic.
Money has always been dirty.
God forbid someone with Covid-19 touched that dollar or penny or Ruble or Dinar or Renminbi or coughed or sneezed on it.
This is a thought that keeps me awake these nights.
Because I love money.
Digital money is the future.
Governments want their tax. Physical money is easy to hide and launder.
So natural progression coupled with Governments of the world wanting their tax money.
Digital money is just an eventuality like the Sun rising in the morning.
would you invest in the Sun rising in the morning? I would.
now with digital money assured. all you need to worry about as far as "dirty" is cleaning your IPhone or Android Screen.
