Isn't worth the cost of the paper it isn't printed on.
If you let your 'money' be swallowed up by the 'cloud' you will rue that day.
When the people no longer have faith in 'paper cash', and that day is soon coming, they will, as always, make haste to gold and silver.
If we get EMP or other catastrophe that sends us back to the communications stone age, ONLY physical coins will be used as 'cash'.
In fact there are many other triggers that could ignite the 'flight to value' that comes when paper is rejected for general transactions.
Not saying that an entrepreneurial person can't make a fortune in fiats then convert it to coin, commodities or land before the next flight to value tho...in fact I wish I was one of those geniuses!
