I am moving from hoarding dollars to holding a currency of value.
So, no attempt at answering the question of who is paying $0.5 million per day so that your currency of value can hold value?
When Google was paying their CEOs in the early days with stock options, were they bringing in the amount of money per day to pay for those stock options in order to hold value?
The inflation created by mining is already priced in.
The inflation is not priced in. It would be priced in if all the minig costs were in BTC. They are not, electricity costs you must pay in a local currency.
There is a reason that they get stock options, and not actual stocks that they could sell on the exchange right away. The reason being that in the early days those quite large amounts of stock would push the price down.
Miners are not paid in BTC options, they are paid in BTC. It is not only that they can sell them right away, they must do so to cover the running costs. Otherwise it is them that are bringing in the fresh money.
So, any other answer attempts on who must pay a large chunk of those $0.5 million daily?
Currently it's 'fresh money' pouring into Bitcoins that's paying for the power expense + miner's profits
This 'fresh money' is stupid because it doesn't understand that mining will bring back Bitcoin's unit price to its real value, zero. The price of bitcoins will trickle down at some point, to zero, not because it wants to, but because it has to.
I myself find this super entertaining to watch that some people are going to lose this rigged game bigtime.
Several people in this game, like Trace Mayer, are trying to put that inevitable loss to the current millionaires of the world by convincing them to buy bitcoins in the press. That's why I love that guy, he'll make our time with bitcoins worthwhile if he succeeds.
Everyone start paying with Paypal and Dwolla again
